Answer:

×= 38

2x-15 = 61°

3×+5= 119°

Explanation:

2×-15+3x +5= 180

180+10= 190

190 ÷5x

×=38

Answer:

a) x = 38

b) 61° and 119°

Explanation:

Same-side Exterior Angles Theorem

When two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the same side of the transversal line are supplementary (sum to 180°).

Part (a)

Using the Same-side Exterior Angles Theorem, equate the sum of the two angles to 180° and solve for x:

⇒ (2x - 15)° + (3x + 5)° = 180°

⇒ 2x - 15 + 3x + 5 = 180

⇒ 5x - 10 = 180

⇒ 5x = 190

⇒ x = 38

Part (b)

Substitute the found value of x from part (a) into the expressions for each angle:

⇒ (2x - 15)°

⇒ (2(38) - 15)°

⇒ (76 - 15)°

⇒ 61°

⇒ (3x + 5)°

⇒ (3(38) + 5)°

⇒ (114 + 5)°

⇒ 119°

Therefore, the two angles are 61° and 119°.
