Answer:
so the labelled angles are 30 and 90, but it only shows one 90. In fact there are 4 angles of 90. The marked 90 then the vertical angle and the complementary angles. All triangles equal 180 so the given 30 and 90 are taken from the 180.
180 -30-90= 60
But y is the opposite of the 30 which makes y=30
so that leaves x = 60
y=30 and x=60
Answer:
i gotchu. 90 degree clockwise rotation
Step-by-step explanation:
The first step in writing f(x) = 3x² + 6x - 8 in vertex form is
E. Factor out 3 from the first two terms.
f(x) = 3x² + 6x - 8
f(x) = 3(x² + 2x) - 8
f(x) + 8 = 3(x² + 2x + __)
f(x) + 8 + 1 = 3(x² + 2x + 1)
f(x) + 9 = 3(x+1)²
f(x) = 3(x+1)² - 9
Answer:
4:5
Step-by-step explanation:
half of 16 is 8, and half of 8 is 4
and half of 20 is 10, and half of 10 is 5
hope i helped man
