A circle is 360°.
Add the known angle measures and subtract the total from 360°.
115+105+60 =280°
360 - 280 = 80°
X= 80°
Answer:
Step-by-step explanation:

x₁ - 6 = -5 *2 ; y₁ - 3 = -5*2
x₁ - 6 = - 10 ; y₁ -3 = -10
x₁ = -10 +6 ; y₁ = -10 +3
x₁ = -4 ; y₁ = -7
Endpoint(-4, -7)
Answer:
False.
Step-by-step explanation:
it is an angle formed by 2 adjacent sides inside the polygon.
Replace w with 10 and solve for a:
10 = (a-7000/2000 + 2)
Subtract 2 from both sides:
8 = a-7000 /2000
Multiply both sides by 2000:
16,000 = a-7000
Add 7000 to both sides:
a = 23,000
You can climb 23,000 feet
The explanation is replacing w with the number of weeks ( 10) and solving for a. You can then check by replacing a with the solution and solving for w.
Answer:
4 1/4
Step-by-step explanation:
Complementary angles add up to 90 degrees.
Thus if 12q - 9 and 8q + 14 are complementary,
12q - 9 + 8q + 14 = 90.
Combining like terms, we get:
20q + 5 = 90
20q = 85
Thus, q = 85/20, or 17/4, or 4 1/4
