Answer:
Step-by-step explanation:
An obtuse angle in the triangle is opposite to the greatest side. The greatest side in the triangle with sides lengths 2, 2 and 3 is side with length 3. By the cosine rule,
7/8 = 87.5%
I'm guessing it is meant to say round to the nearest 10th of a percent

Answer:
x = 3.9
Step-by-step explanation:
So the whole angle PQS = 111 degrees
it gave you part of it so subtract that off . 111 - 72 = 39 degrees
10 times what equals about 39 degrees.
39/ 10 = 3.9
Answer:
x = 12, y=7
x=30, y=25
x=15, y=10
Step-by-step explanation:
We have : y = x - 5
x = 12 then y = 7, y = 12 - 5 = 7
x = 30 25 = x - 5, x = 25 + 5 = 30
x = 15, y = 15 - 5 = 10, y = 10
