Answer:
angle Y= 60 degrees
Step-by-step explanation:
angle S + angle Y = 90 degrees because they are complementary
Y = 90 - S
angle S = 4(Y)-210
substitute for Y
S = 4(90 - S) - 210
S = 360 - 4S - 210
reduce
5S = 150
S = 30
Y = 90 - 30 = 60
Answer:
She incorrectly multiplied 15 X 1/4
Step-by-step explanation:
To solve this problem, we just need to set up a simple equation. We have that angles 1 and 2 add up to equal a right angle, or 90°, and that m<2 is 35°, so we just have to do a bit of subtraction.
<1 + <2 = 90 Given
<1 + 35 = 90 Substitute 35 for <2
<1 = 55° Subtract 35 from both sides to get rid of it, since subtraction is the opposite of addition.
Therefore, m<1 = 55°.
Hope this helps!
Answer:
The answer to your question is (g°f)(x) = 7
Step-by-step explanation:
Data
g(x) = 3x - 2
f(x) = x + 5
(g°f)(-2)
Process
1.- Evaluate g(x) on f(x)
(g°f)(x) = 3(x + 5) - 2
-Expand
(g°f)(x) = 3x + 15 - 2
-Simplify
(g°f)(x) = 3x + 13
2.- Evaluate (g°f)(x) on -2
(g°f)(-2) = 3(-2) + 13
-Expand
(g°f)(-2) = -6 + 13
-Simplify
(g°f)(x) = 7
