Answer:<1=126° <2=54°
Step-by-step explanation:
sum of angles in a =180°
<2+90+36=180
<2+126=180
Collect like terms
<2=180-126
<2=54°
<2 and <1 are supplementary angles therefore their sum is equal to 180
<2 + <1=180
54 + <1=180
Collect like terms
<1=180-54
<1=126
1 root.
x^2 = 64 has 2 roots, -8 and 8.
But x is less than 0, so only -8 is a root.
First of what does a equal?
