The tangent ratio of ∠A is
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
The total distance between the airplane and the runway is 14102 ft.
The total height distance between the airplane and the runway can be solved through the equation:
14,080 ft + 22ft = <span>
14102 ft</span>Since the runway is below sea level, it adds to the total distance.

If you have two equations, you will multiply one of them so it cancels out the other one. For Example, 2x-y=16 3x-y=28You will multiply the second equation by -1 which brings us to 2x-y=16 -3x+y=-28you will add both equations together which will leave you with-x=-12x=12Then, you plug that in. 2x12=24. 24-16=8. 3x12=36 36-8=28 And, You're done!
Percent increase : (new number - original number) / (original number)....then multiply that by 100 to get ur percent.
(5.98 - 4.6) / (4.6) = 1.38/4.6 = 0.3......0.3 x 100 = 30% <==
