One of the congruent angles of the isosceles triangle given above is 40° which means that the other angle, mPRQ is also 40°. Knowing that the sum of the angles of a triangle is 180°, mPQR may be calculated by,
mPQR = 180 - (mPRQ + mQPR)
Subsituting the given,
mPQR = 180 - (40 + 40) = 100°
Thus, the answer is 100°.
Answer:
73.5
Step-by-step explanation:
Step 1: 21/2 divided by 2 = 21/4
Step 2: 21/4 times 21/4 times 8/3 =
Answer: 73.5
The green shaded box is there to show that that is the base are to find the two sides that were multiplied to get that do the first step. Then do your basic volume formula: length times width times height.
here's the right answer!
A) 76 + 80 + 78 + x = 82 times 4
234 + x = 328
x = 94
B) Mei needs a score of at least 94 on the next exam.
hope you have a good day
Answer:
26,812 ft
Step-by-step explanation:
The drawing given is very helpful in this case. When solving problems like this, it's important to realize what trigonometric ratio we're going to use. From the given angle (50°), we are given the hypotenuse (35,000 ft) and we're trying to solve for the opposite side ().
So since we're trying to find the opposite side side and we have the hypotenuse, we should try to find a trigonmetric ratio between the opposite side and the hypotenuse. Using SOH-CAH-TOA, hopefully you can see that we should pick SOH (i.e. ). Therefore, we can set up our equation given the angle .
Since we're solving for , we can just rearrange to get
Therefore, the plane's altitude is 26,812 ft.
Answer:
area of circle=πr²=1.3mi²
we have
area of sector=∅/360×πr²
0.7mi²×360=∅1.3
∅=0.7×360/1.3=193.846°×π/180=387.7 radian
