Answer:
165
Step-by-step explanation:
c = 6 and d = 10
= 5 × 6² = 5 × 36 = 180
- ( 3 d ) = 180 - ( 3 × 10 ) = 180 - 30 = 150
- 3 d ( + 15 ) = 150 + 15 = 165
Answer:
Larger angle: 80 degrees
Smaller angle: 10 degrees
Step-by-step explanation:
complementary angles = two angles that add up to 90 degrees
x = larger angle
x + x - 70 = 90 Add like terms
2x - 70 = 90 Add 70 on both sides
2x = 160 Isolate the variable by dividing 2 on both sides
x = 80
x = larger angle , 80 degrees
x - 70 = smaller angle , 10 degree

Answer:
X = 12 Y = -29
Step-by-step explanation:
X+Y= -17
X-Y=41
Solve for y in first equation
Y=-17-x plug y into the 2nd equation
X-(-17-x)=41
X+17+x=41
2x=41-17
2x=24
X=12
Y=-17-(x)
Y=-17-12
Y=-29
X+Y=-17
12+-29=-17
X-Y=41
12- -29=41
