I don’t get this please help me if your smart u get 10 points

112

Step-by-step explanation:

Supplementary angles means that angle A and angle B added together equal 180˚. This mean we can re-write the angle measures into an algebra problem

A(3x+16) + B(2x + 4 ) = 180

Or

5x + 20 = 180

5x + 20 - 20 = 180 - 20

5x = 160

5x/5 = 160/5

x = 32

Now that we know that X = 32, we can plug 32 into the measure of angle A.

A(3x+16)

A(3(32)+16)

A(96+16)

A(112)

Angle A equals 112˚ and Angle B equals 68˚.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

pls mark as brainliest

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
