Answer:

a. 74°

Step-by-step explanation:

Angle BCD and angle ACB are supplementary because they form a straight line. This means they add up to 180. We can write an equation to model the situation:

m<BCD + m<ACB = 180

106 + m<ACB = 180

m<ACB = 74

Since we are given two sides of the triangle are congruent, the triangle is isosceles. The base angles of an isosceles triangle are congruent, so we can say:

m<ACB = m<A

This means m<A is equal to 74°

Which equation is parallel to<br> y =2/3x – 6 and passes through (9, -3)?

SpyIntel [72]

Answer:

y=2/3x -3

Step-by-step explanation:

y=mx+c

If the gradient(m) is the same then it's parallel.

The line passes through -3 so the y intercept(c) is -3

What is the value of the expression? 1 1/3 x 2/7

natka813 [3]

Answer:

$\frac{2}{21}$

Step-by-step explanation:

First, apply the fraction rule.

$\frac{1}{3}\cdot \frac{2}{7}=\frac{1\cdot \:2}{3\cdot \:7}$

$=\frac{1\cdot \:2}{3\cdot \:7}\\$

Then, I multiplied the numbers on top.

$=\frac{2}{3\cdot \:7}$

Finally, I multipiled the numbers on the bottom.

$=\frac{2}{21}$

Hope this helps, and have a blessed day!

Solve for<br> 8 - 6r + 3 = 5

Oksanka [162]

Answer:

r = 1

Step-by-step explanation:

8 - 6r + 3 = 5

Combine like terms

11 - 6r = 5

Subtract 5 from both sides

6 - 6r = 0

Add 6r to both sides

6 = 6r

Divide both sides by 6

1 = r
