1. .35(15) + .72(5) = 8.85
2.8.85/(15 + 5) = 0.4425 = 44.25%Answer:
Step-by-step explanation:
Answer:
6. x=53 obtuse
7. x=120 obtuse
Step-by-step explanation:
To find x, you need to add up the angle measures you already have and subtract that sum from 180.
For example, on number 6 you have 37 and a right angle (that little box in the corner). That counts as 90, so its 90+37=127. Then, you subtract 180-127=53. That is how you get your answer.

Answer:
Step-by-step explanation:
<u>Solution 1:</u>
Recall that in an isosceles triangle, the two angles adjacent to the congruent sides are equal. Since the sum of interior angles in a triangle add up to 
, we set up the following equation:
.
Solving, we get:
.
<u>Solution 2:</u>
The Law of Sines states:
, for any triangle.
We can use this to set up a proportion with the information given:
.
Solving, we get:
.
