I am pretty sure.
Answer:
Step-by-step explanation:
Positive integers have values greater than zero. Negative integers have values less than zero.
Since the angle are both 45 degrees, then you know that both legs are equal=12.
so to find the hypotenuse, you use the pythagorean theorem:
12^2+12^2= c^2
144+144=c^2
288=c^2
square root(144) x square root (2)=c
12 square root 2 is the answer, so D.
Answer:
Q19 - x = 7
Q20 - x = 24
Step-by-step explanation:
Q19.
75 + x + 8 = 90°
83 + x = 90°
x = 90 - 83
<u>x = 7</u>
<u>{</u>CHECK: 75 + 7 + 8 = 90°<u>}</u>
<u></u>
Q20.
3x - 6 + x = 90°
4x - 6 = 90°
4x = 96
x = 96 / 4
<u>x = 24</u>
<u>{</u>CHECK: 3(24) - 6 + 24 = 90°<u>}</u>
<u></u>
