Answer is B if it isn’t I’m sorry
ANSWER: y=9
First substitute x
6.4(3)+2.8y=44.4
19.2+2.8y=44.4
subtract 19.2 from both sides
2.8y=25.2
divide by 2.8 on both sides
y=9
First find the length of the longest leg
x^2 = 13^2 - 5^2 ( by the Pythagoras theorem)
x^2 = 144
x = 12
Area of the traingle = 1/2 * base * height
= 1/2 * 5 * 12
= 30 units^2
Answer:
m∠QPR = 31°
Step-by-step explanation:
So, let's keep in mind that QPS = 47 Degrees
Given that, we find that 3x - 38 + 7x - 95 = 47
from this, 10x - 133 = 47
then => 10x = 180
x = 18
So now we plug it in
--> 3(18) - 38 = RPS
54 - 38 = 16
RPS = 16 Degrees
--> 7(18) - 95 = QPR
126 - 95 = QPR
QPR = 31 Degrees
and Thus, m angle QPR is equal to 31 Degrees
Checks:
16 + 31 = 47
Total = 47
So it is correct
