Answer:
Step-by-step explanation:
<u>Use the formula for angle formed by the chords:</u>
- Angle formed by 2 chords = 1/2( sum of intercepted arcs)
<u>Let the supplementary angle of x be y</u>
- x + y = 180 (straight angle)
<u>Find the value of y, using the above mentioned formula</u>
- y = 1/2(168 + 40) = 1/2(208) = 104
<u>Find the value of x:</u>
- x = 180 - y
- x = 180 - 104 = 76
Correct choice is C
We have been given that in ΔBCD, the measure of ∠D=90°, the measure of ∠C=42°, and CD = 7.5 feet. We are asked to find the length of DB to nearest tenth of foot.
First of all, we will draw a right triangle using our given information.
We can see from the attachment that DB is opposite side to angle C and CD is adjacent side to angle.
We know that tangent relates opposite side of right triangle to adjacent side of right triangle.
Therefore, the length of DB is approximately 6.8 feet.
P= k/Q
16.4= k/123
k= 16.4 * 123
k= 2017.2
Therefore, P= 2017.2/Q
We are given the price if each ticket, the amount raised, and how many tickets that the STUDENTS sold. So we know that Children tickets cost $3 and adult tickets cost $5, and we also know that they raised $1025. If the students sold 275 tickets, we can assume that these tickets sold by the students where sold TO other students, meaning that we would take 275x3=825 and then use that for 1025-825=200 then use that for 200/5=40 so in total, 40 adult tickets where sold and 275 children tickets where sold. 275+40=315 tickets sold
Divide each part of the equation with 4. Then y is equal to 6.
