Answer:
m∠C = 38° (nearest whole number).
Step-by-step explanation:
To find the missing angle, use the Sine Rule.
<u>Sine Rule</u> (for angles)

where:
- A, B and C are the angles
- a, b and c are the sides opposite the angles
Given:
To find m∠C, substitute the given values into the formula and solve for C:




Therefore, m∠C = 38° (nearest whole number).

The answer is 170. First you add base one and base two divide by twi the multiply that by the height. 18+22=40 40/2=20 20•8.5=170
Answer:
-3
Step-by-step explanation:
Isolate -3y by subtracting x from both sides
-3y = -18 - x
Divide everything by -3
y = 6 + 1/3x
Slope is 1/3, and perpendicular lines have the reverse reciprocal slope, so our slope is -3

srry if it's wrong cuz I dont remember some of these but I tried
Answer:
true
Step-by-step explanation:
all the sides match up. One side (the base) is shared which means they are the same length. The triangle at the top has a single hash on a side and so does the bottom one. This means they are the same length. The same thing occurs with the last remaining sides, they are congruent because they both have two hash lines. Since all three sides of both triangle add up, the triangles ARE CONGRUENT.
