Answer:
The answer for ∠B = 68°
Step-by-step explanation:
Total angle in a triangle is 180° so you can just substract ∠A and ∠C from 180° :
∠A + ∠B + ∠C = 180°
90° + ∠B + 22° = 180°
∠B = 180° - 90° - 22°
= 68°
D. (2,3)
Explanation:
We already know that x=2, so of we plug in 2 for x, we should get the y value.
Once we plug in 2 for x we should get the equation:
2(2)+3y=13.
Simplify that and we get:
4+3y=13.
Subtract 4 from both sides and we get:
3y=9.
Divide both sides by 3 and we get:
y=3.
This means that your ordered pair should be (2,3).
Hope this helps :)
The equation would be c÷3=7 (haha i think thats the answer)
