Help please. Us the diagram to find the measure of each arc. Give an 80 and MUR diameters measurement of angle BRT was 80° and measurement of angle ARM equals 60°.

(I) BT = 80°

(II) AUB = 240°

(III) MB = 60°

Explanation:

Given:

∠ARM = 60°

∠BRT = 80°

(i) BT = ?

According to the figure, BT = 80°

(ii) AUB = ?

∠MRB = 180 - ( 80 + 60 )

∠MRB = 180 - 140

∠MRB = 60°

AUB = 360 - ( 60 + 60 )

AUB = 360 - 120

AUB = 240°

(III) MB = ?

MB = 180 - ( AM + BT )

MB = 180 - ( 80 + 60 )

MB = 180 - 140

MB = 60°

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
