What is the measure of angle A? And what is the length of AB?

∠A=53, and AB=13.7734922397

Step-by-step explanation:

Angles in a triangle add up to 180.

∠A+∠B+∠C=180

∠A+37+90=180

∠A=53

Use sine rule:

x/sinX=y/sinY

AB/sin∠C = CB/sin∠A

AB/sin90 = 11/sin53

AB/1=11/0.79863551004

AB=13.7734922397

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
