Answer:
- 40
Step-by-step explanation:
Two angles are complementary: x + y = 90 (complementary = 90 degrees)
x = 2y
plug in 2y for x
2y + y = 90
3y = 90
3y/3 = 90/3
y = 30
plug in 30 for y
x = 2y
x = 2(30)
x = 60
x (the largest angle) = 60°

Answer:
1
Step-by-step explanation:
9-7 = 2 (-2)
1-3 = -2
-2/-2 = 1
Answer: True for all <em>b</em>.
Step-by-step explanation: To tangent a equation, find if the variable is true.
1. Add 56 to both sides.
63b - 56 + 56 = 63b - 56 + 56 = 7
2. Simplify.
63b = 63b
3. Simplify again for your answer.
0 = 0
Hence, both sides are equal.

X+y=-1
3x-y=21
add them equations
x+y=-1
<u>3x-y=21 +</u>
4x+0y=20
4x=20
divide by 4
x=5
x+y=-1
5+y=-1
minus 5 both sides
y=-6
(x,y)
(5,-6)
