I'll tell you how to find the answers and just use the give angle measure to solve.

9) angle 11 = angle 14
10) angle 9 + angle 15 = 180
11) angle 10 = angle 3
12) angle 7 = angle 14

If the area of a triangle is 28in2 and the height is 8 inches, determine the length of the base.

klemol [59]

area of triangle formula = ½ × B × H

28in2 = ½ × B × (8)

28in2 = 4 × B

28 ÷ 4 = B

Therefore, length of base = 7 inches

For which values of a, b, and c will Ax+ By=C be a horizontal line through the point (-4,2)

RUDIKE [14]

Answer:

A = 0, B = 1 and C = 2

Step-by-step explanation:

The slope of a horizonal line is zero.

y = mx + b Use the slope intercept form with m = 0 and point (-4, 2).

2 = 0(-4) + b Solve for "b"

2 = 0 + b

2 = b

The equation in slope intercept form is y = 0x + 2 ; y = 2.

The equation in standard form: Ax + By = C has the value 0x + y = 2
