Math Response
WARMUP: X is in the interior of ∠BLM. If m∠BLM = 27° and m∠XLB = 23°, then m∠XLM = ___ °
4
A is in the interior of ∠BNJ.
If m∠BNA = (2x)°, m∠ANJ = (5x)°, and m∠BNJ = 84°. Find x.
5
Math Response
S is in the interior of ∠TRQ.
If m∠TRS = (4x)°, m∠SRQ = (7x)°, and m∠TRQ = 88°. Find x.
6
S is in the interior of ∠TRQ.
If m∠TRS = (4x)°, m∠SRQ = (7x)°, and m∠TRQ = 88°.
Find m∠TRS.
Find m∠SRQ.
This is a continuation of the problem you JUST did where x = 8.
7
S is in the interior of ∠TRQ.
If m∠TRS = (2x)°, m∠SRQ = (6x)°, and m∠TRQ = 104°.
Find m∠TRS.
Find m∠SRQ.
