Whats the measure of the angles (SHOW YOUR WORK so I can understand)
evablogger [386]

Answer:

Angle DEB: 52

Angle ADB: 30

Angle CBE: 52

Angle BEC: 38

Step-by-step explanation:

Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.

can somebody please help my friend, she has asked everyone she knows and nobody knows how to solve it. please help ty​
Nady [450]

Answer:

42

Step-by-step explanation:

First I'm going to assume that C and A are perpendicular.

Because its perpendicular, this creates a 90 degree angle which can be used to create the following equation.

90 = 6x - 6 + 5x + 8

Reduce

11x = 88

x = 8

We then plug in 8 into the equation 6x - 6 in order to solve for that angle.

6(8) - 6

What is 15=-3y+21x in slope intercept form?
sweet [91]
Slope intercept form = Y = Mx + B

15 = -3y + 21x

3y = 21x - 15

Y = 21/3 X - 15/3

Y = 7x - 5 = SI Form
