Please help find the top angle

Mathematics
1 answer:
ziro4ka [17]3 years ago
3 0

Answer:

130 degrees

Step-by-step explanation:

So u can see those little lines on two of the sides of the triangle, it means that it's congruent also meaning the same length, and if u didn't, the angles had to be the same in order for the sides to be the same length. So the other missing angle degree is also 25 degrees. A triangle is 180 degrees, so with this info:

25 + 25 + 4x + 2 = 180

4x + 52 = 180

4x = 128

x = 32, now we have x so replace the x in the equation with 32

4(32) + 2

128 + 2

130

The distance around the middle of a sphere (the circumference) equals 37.699 in. what is the surface area of the sphere?
podryga [215]

To solve this problem you must apply the proccedure shown below:

1. Clear the radius from the formula for the circumference of a circle and substitute values, as following:

C=2\pi r\\ r=C/2\pi \\ r=37.699in/2\pi \\ r=5.99in

2. Substitute the radius calculated into the formula for calculate the surface area of the sphere:

SA=4\pi r^{2} \\ SA=4\pi(5.99in^{2})\\ SA=450.88in^{2}

The answer is: 450.88in^{2}

inn [45]

Answer:

\displaystyle \large{y=36}
