Answer:
Check pdf
Step-by-step explanation:
55.77°
EXPLANATION:In ◣ ABC, (consider the diagram)
cosΦ = b/h = 9/16
cosΦ = 9/16
Φ = 9/16 × cos-¹
Φ = 55.77
Hence, the angle between the ladder and ground is approximately 56°.

If u can solve 6 word problems in 5 minutes how many could you solve per minute?
Answer:
You can solve 1.2 word problems per minutes
Step-by-step explanation:
If 6 word problems were solved in 5 minutes, you must put this into a fraction. We're looking for how many word problems could be solved per minute, so we divide 5 by itself to get 1 and whatever you do to the bottom, you must do to the top, so 6 divided by 5 is 1.2

Find the values of x, y and z.
Answer:
X = 53 degrees
Y = 74 degrees
Z = 53 degrees
Step-by-step explanation:
So if you knew that all angles in triangles add up to 180 degrees. You first want to find Y. 180 - 36 - 70 is equal to 74. So, Angle Y is 74 degrees. Line XYZ is a line that has a 180 degree on there. So 180 - 74 and divide that by 2 to find X and Z. 180 - 74 is 106. 106/2 = 53. Therefore, X and Z are 53 degrees, Y is 74 degrees.
Y =74
Step-by-step explanation:
Add the number till u get 180

Answer:
[tex] \frac{ \sqrt{7} }{2} [/tex]
Step-by-step explanation:
The triangle is an isosceles triangle. Because the triangle is an isosceles triangle, the height and base of the triangle are equal to eachother.
a² + b² = c²
right now we have c² which is 7
a² + b² = 7
[tex] \frac{ \sqrt{7} }{2} [/tex]
because a² and b² are = to eachother

Step-by-step explanation:
Triangle P N M is shown. The length of P N is 7, the length of N M is 8, and the length of M P is 11.
Law of cosines: a2 = b2 + c2 – 2bccos(A)
Which equation correctly applies the law of cosines to solve for an unknown angle measure?
72 = 82 + 112 – 2(8)(11)cos(N)
82 = 72 + 112 – 2(7)(11)cos(M)
72 = 82 + 112 – 2(8)(11)cos(P)
82 = 72 + 112 – 2(7)(11)cos(P)
Answer:
8^2 = 7^2 + 11^2 – 2(7)(11)cos(P)
D.
Step-by-step explanation:
Edge 2021
The equation correctly applies the law of cosines to solve for an unknown angle measure is equation D.
What is a Triangle?A triangle is a polygon with three sides, three vertices, and three angles.
The length of P N is 7,
The length of N M is 8, and
The length of M P is 11.
The law of cosines is used to determine the missing sides and angles if two sides and an angle are given or three sides are given respectively.
The equation that correctly applies should have the two sides and the cosine of the included angle.
The correct equation is 8² = 7² + 11² – 2(7)(11)cos(P)

Answer:
∠QSR = 78°∠SQR = 51°Step-by-step explanation:
The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...
∠QSR = 2×∠QTR
∠QSR = 2×39°
∠QSR = 78°
__
Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...
∠QSR + 2(∠SQR) = 180°
78° + 2(∠SQR) = 180° . . . . fill in the value we know
2(∠SQR) = 102° . . . . . . . . . subtract 78°
∠SQR = 51° . . . . . . . . . . . . .divide by 2
