<u>Answer:</u>
Angle Z = 117°
<u>Step-by-step explanation:</u>
We are given a figure with a triangle with two known angles and one unknown angle. That unknown angle further extends to form a straight line and we are to find that exterior angle z.
We know that the sum of all three angles of a triangle is 180°. So the third unknown angle of the given triangle will be = 180 - (45 + 72) = 63°.
We also know that angles on one side of a straight line always add to 180°.
Therefore, angle z = 180 - 63 = 117°.

Answer:
15 ml
Step-by-step explanation:
We will use a proportion to solve this problem. A proportion is setting a ratio equal to another ratio.
We start with the known ratio.
ratio of A to B = A/B = 3/2
Now we write the ratio that contains A as an unknown.
We want the amount of solution B to be 10 ml. Let the amount of solution A be A.
The ratio is A/10.
A/10 and 3/2 must be equal.
A/10 = 3/2
When you set two ratios equal, you have a proportion.
Now we solve the proportion for A.
Cross multiply.
2 * A = 10 * 3
2A = 30
A = 15
Answer: 15 ml
Answer:
The Pythagorean theorem formula is
a²+b²=c²
Step-by-step explanation:
Here's an example
a²+b²=c²
8²+6²=c²
64+36=c²
100=c²
c=√100
