Answer:
135°
Step-by-step explanation:
In a parallelogram the opposite angles are congruent, so
∠BCD = ∠BAD = 135°
Answer:
<h3> C. y + 7 = -7(x - 3)</h3>
Step-by-step explanation:
The equation of a line is:
y - y₀ = m(x - x₀)
where <em>m</em> is the slope and <em>(x₀, y₀)</em> is the point which the line passes through
The product of slopes of two perpendicular lines is -1
so if given lines slope is ¹/₇ them:
¹/₇·m = -1
m = -7
(3, -7) ⇒ x₀ = 3, y₀ = -7
Therefore:
y - (-7) = -7(x - 3)
<u> </u><u>y + 7 = -7(x - 3) </u>
Answer:
90
Step-by-step explanation:
a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90
15. A=7, 16. V=9, 17. D=26
Answer:
A
Step-by-step explanation:
6.99 - 6 = 0.99
8 - 6.99 = 1.01
1.01>0.99
So it's A
