Can you take another fully picture plez
Answer:
do you have a picture or something
Step-by-step explanation:
Answer:
m∠QRT = 90°
m∠QRT = m∠SRT
Step-by-step explanation:
Triangle QST is isosceles with QT ≅ ST. In isoscels triangle QST, angles STR and RTQ are congruent.
RT is angle T bisector, so angles QTR and STR are congruent.
Consider two triangles QTR and STR. In these triangles:
- TR ≅ TR (reflexive property);
- ∠QTR ≅ ∠STR (given);
- QT ≅ ST (given).
By SAS postulate, these two triangles are congruent. Two congruent triangles have congruent corresponding sides, so
Angles QRT and SRT are supplementary (add up to 180°). Since these two angles are congruent, they have the same measure equal to 
So, true options are
m∠QRT = 90°
m∠QRT = m∠SRT
Answer:
You should solve it using system. because we have two unknown values here.
the first equation should be
8y + 17 = 180
the second
17 + 7x = 180
