Answer: 63%
Step-by-step explanation:
<u>First step</u>
Find the 10th year rate of loss that will make the average of loss over the 10 years to equal 38.0%.
Assume this rate is x;
x = 37%
<u>Second step - Survival rate</u>
The survival rate is calculated by;
= 1 - rate of loss
= 1 - 37%
= 63%
<u>Answer:</u>
<u>Step-by-step explanation:</u>
The sum of interior angles of a quadrilateral is 360°.
If we consider the measure of one of the unknown angles to be °, we can set up the following equation:
Now we can solve for :
⇒
⇒ [subtracting 192° from both sides]
⇒
⇒ [dividing both sides by 2]
⇒
Therefore, the other two angles each have a measure of 84°.
