3rd option and 2nd option

Step-by-step explanation:

(10)

A linear pair sum to 180° , then

x - 30 + x + 76 = 180 , that is

2x + 46 = 180 ( subtract 46 from both sides )

2x = 134 ( divide both sides by 2 )

x = 67

Then

∠ 1 = x - 30 = 67 - 30 = 37°

∠ 2 = x + 76 = 67 + 76 = 143°

(11)

Since T is the midpoint of SU , then

ST = TU , that is

5x = 3x + 32 ( subtract 3x from both sides )

2x = 32 ( divide both sides by 2 )

x = 16

Then

ST = 5x = 5(16) = 80

TU = 3x + 32 = 3(16) + 32 = 48 + 32 = 80

SU = 5x + 3x + 32 = 8x + 32 = 8(16) + 32 = 128 + 32 = 160

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
