Step-by-step explanation:
ΔSTR and ΔSQR are similar triangles
so TR/SR=SR/QR
--> q/14=4/q
--> q = 2
Answer:
3x + x + 100° = 180°
⇔ 4x = 80°
⇔ x = 20°
Step-by-step explanation:
Answer:
y=3/10;X=-7/10
Step-by-step explanation:
put y=x+1 into where you find y.
solve for X which is -7/10
and put -7/10 into the second equation and solve for y. which is also =3/10
Answer:
6+3x
You remove the parentheses and multiply
