Find the missing angle measure.

Will give brainliest if possible!!

Answers

Answer: 35°

Step-by-step explanation:

Step #1: Write the 'triangle sum theorem' for the triangle which is:

m∠A + m∠B + m∠C = 180°

Step #2: Substitute the given angle measures

40° + 105° + m∠C = 180°

Step #3: Simplify.

m∠C + 145° = 180°

Subtract 145° from both sides.

m∠C = 35°

So, the measure of the missing angle (x) is 35°.

Okay here is your answer

2. Find Each Angle Measure

Answers

Answer:

m∠1= 31° m∠2=149°

m∠3= 31° m∠4=149°

m∠6=31° m∠7=149°

m∠8=31°

Step-by-step explanation:

m∠1 + m∠5= 180°

m∠1=180-149

m∠1=31°

m∠2+m∠1=180

m∠2=149°

m∠6=31°

m∠3=m∠1 (corresponding angle)

m∠3=31° m∠8=31° (vertical angle)

m∠4=149° m∠7=149° (vertical angle)

Jackson paints? Be sure to show your work and explain your reasoning.
Part B
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Part C
Jackson has a second cube identical to the first. He cuts off the triangular prism as shown below and throws
it away.
What is the volume, in cubic centimeters, of the remaining solid? Show or explain all your work.

Answers

Answer:

Part A- Surface area = 150cm squared

Step-by-step explanation:

First you find the area of one side of the cube-

side length (5) x side length (5) = area (25)

25 is the area of one side of the cube.

Then you multiple the area of one side (25) by the amount of sides that there are (6)-

25 x 6 = 150

What is the probability of getting exactly 2 tails?

Enter your answer as a reduced fraction, like this: 3/14

Answers

Answer:

or 2/3

Step-by-step explanation:

because two flips out of 3 all together is 2/3

Flipping a coin to get H or T is a 50% (0.5) chance respectively
So to get 2 tails we could have gotten:
H T T
T T H
T H T
— P( H T T) = 0.5 x 0.5 x 0.5 = 0.125
— P(T T H) = 0.5 x 0.5 x 0.5 = 0.125
— P(T H T) = 0.5 x 0.5 x 0.5 = 0.125
0.125 + 0.125 + 0.125 = 0.375 = 3/8

Only answer if you know 100% if you get it right I'll give brainliest

Answers

hello!

let's write 2*2*2*2*2*2*2*2*2 in exponential form.

Notice 2 has been multiplied times itself 9 times.

Basic exponential notation:-

[tex]\sf{2*2=2^2}[/tex]

[tex]\sf{2*2*2=2^3}[/tex]

[tex]\sf{2*2*2*2=2^4}[/tex]

You should notice a pattern.

This is the pattern:-

The number of times 2 has been multiplied times itself is the exponent.

In this case, we multiplied 2 times itself 9 times.

Hence, the answer is

The actual gallery comes to be 84 feet long.

What is a scale factor?

A scale factor is a factor by which the dimension of an object is enlarged or diminished.

Scale of 2 inches = 7feet.

So, a scale of 1 inch = 7/2 feet

So, scale factor =7/2

So, a scale of 24 inches = 24*scale factor= 24*7/2 = 84 feet

So, the actual length of the gallery = 84 feet

Therefore, the actual gallery comes to be 84 feet long.
