Answer:
3 c
Step-by-step explanation:
In triangle STU, the possible values for ∠S, derived by using the law of sines, are approximately 10.2° and 169.8°.
The student wants to find all possible values of ∠S in ΔSTU, s=1.6 cm, u = 9.5 cm and ∠U=24°. This is a problem involving the laws of sines and cosines in trigonometry. By using the law of sines, we can find ∠S = sin⁻¹ ((sin U * s) / u) ≈ 10.2° or 169.8° (since sinx is positive in both the 1st and 2nd quadrants). It is important to note that ∠S and ∠U are not complimentary angles in a right triangle, therefore, both possible values of ∠S are valid if they meet the condition that the sum of ∠S, ∠T and ∠U should be equal to 180° in ΔSTU.

Answer:
3w + 52 ≥ 90
Step-by-step explanation:
If she volunteers 3 hours per week for w weeks, then the number of hours from tutoring is 3w. Add the 52 hours from her summer volunteering, and her total hours is 3w + 52. This needs to be at least 90 hours for her to graduate, so:
3w + 52 ≥ 90
Answer:
The solution to the inequality is;
x > -7/3
Step-by-step explanation:
We want to find the solution to the inequality;
-3x + 8 < 15
We can have this as;
-3x < 15-8
-3x < 7
x > -7/3
Answer:
x>-7/3

Answer:
Angles of △EFQ:
m<EFQ = 100°
m<EQF = 14°
m<FEQ = 66°
Step-by-step explanation:
ED is the diameter of the circle O
so m<EFD = 1/2 (180) = 90°
Given m∠DFQ = 10°
△EFQ
m<EFQ = m<EFD + m∠DFQ = 10° + 90° = 100°
arc EF = 28°,
so m<EQF = 1/2 (28) = 14°
m<FEQ = 180 - ( 100° + 14°) = 66°
Answer:
m<EFQ = 100°
m<EQF = 14°
m<FEQ = 66°
