Area = π r²
area of the required sector = (80/360) π * 15²
≈ 157.08
4ax+12-3ax=25+3a
Ax+12=25+3a
Ax=25-12+3a
Ax=13+3a
X=13/a+3

6 + 8x
Step-by-step explanation:
Answer:
The first one is A The second one would be D
Step-by-step explanation:
<2 = 45 degrees They are corresponding angles
74 + <1 + <2 = 180 it makes a straight line
74 +<1 +45 = 180
119 +<1 =180
subtract 119
<1 = 180 -119
<1 = 61 degrees
