Angle Addition Postulate (Part 1)

Objective: Find and angle measurements using the Angle Addition Postulate.

Math Response

WARMUP: X is in the interior of ∠BLM. If m∠BLM = 27° and m∠XLB = 23°, then m∠XLM = ___ °

Type answer here

Correct Answer: 4

Deg^°

Rad

EXAMPLE

A is in the interior of ∠BNJ.

If m∠BNA = (2x)°, m∠ANJ = (5x)°, and m∠BNJ = 84°. Find x.

Math Response

S is in the interior of ∠TRQ.

If m∠TRS = (4x)°, m∠SRQ = (7x)°, and m∠TRQ = 88°. Find x.

Type answer here

Correct Answer: 8

Deg^°

Rad

EXAMPLE

S is in the interior of ∠TRQ.

If m∠TRS = (4x)°, m∠SRQ = (7x)°, and m∠TRQ = 88°.

​

Find m∠TRS.​
