To find X, set up a ratio with the given dimensions:
10/15 = X/42
Cross multiply:
420 = 15x
Divide both sides by 15:
x = 420 / 15
x = 28
---------------------------------------------
Formula
---------------------------------------------
Sum of all exterior numbers = 360°
---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360
---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360
---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108
---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54
---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°
---------------------------------------------
Answer: 99°

The prisms as indicated in the image attached to the task content have some of their lines solid and some dashed because; the prism is a 3-dimensional figure and all sides must be represented accordingly.
<h3>What is a 3-dimensional geometric figure?</h3>
According to the task content, it follows that the prism as indicated in the image attached to the task content is a 3-dimensional figure.
Also, the solid lines represents the sides visible to the observer, while the dashed lines represents the side areas which are invisible to the observer.

Answer:
100
Step-by-step explanation:
well, you can just use a calculator, or your mind if that's possible, to solve this.
at least, what i think you're asking.
400 × 0.25 = 100.
this one is extra easy because you should know that 25% is a quarter, and 400 can just be divided by 4 to get your answer.
The answer is all four parts
