Solve for x. Round to the nearest tenth, if necessary.
serg [7]

Answer:

x = 8.8

Step-by-step explanation:

take 20 degree as reference angle .the,

hypotenuse = OQ = x (hypotenuse is always opposite of 90 degree)

perpendicular(opposite) = PQ 3 (opposite of reference angle is perpendicular or also called as opposite)

base(adjacent) = OP (side which lies on the same line where 90 degree and reference angle)

using sin rule

sin 20 = opposite / hypotenuse

0.34 = 3 / x

x = 3/0.34

x = 8.82

x = 8.8

Solve for m: m + 4 = 5m - 12<br><br> m = 16<br><br> m = 4<br><br> m = 3<br><br> m = -3
kolbaska11 [484]

m + 4 = 5m - 12

Subtract m from both sides.

4 = 4m - 12

Add 12 to both sides

16 = 4m

Divide both sides by 4

m = 4
