I assume you are looking for arc RSQ, since you already now the angle RSQ.
Arc RSQ is 312 degrees.

Since you know angle RSQ, the arc that it creates is twice the angle.
24 x 2 = 48

Arc RSQ is the entire circle (360 degrees) except for that 48 degrees.
360 - 48 = 312

Find the measurements

Elanso [62]

Answer:

angle 2=120°

angle 1=60

Step-by-step explanation:

70+50=120

180-(70+50)=60

angles on a straight line add up to 180°

180-60=120

In the figure, angle D measures 45° and angle E measures 87°. What is the measurement of angle H? 42°

Vinvika [58]

The complete question is shown in the attached image

Answer:
measure angle H = 42°

Explanation:
There is a theorem that states that:
"In a triangle, the measure of the exterior angle is equal to the sum of the measures of the two non-adjacent angles to the exterior angle"

In the given, we have:
angle E is an exterior angle to triangle DFH
The two non-adjacent angles to angle E are angles D and H

Based on the above rule:
measure angle E = measure angle D + measure angle H

We are given that:
angle E = 87°
angle D = 45°

Substitute with the givens in the above rule and solve for the measure of angle H as follows:
angle E = angle D + angle H
87° = 45° + measure angle H
measure angle H = 87° - 45°
measure angle H = 42°

Hope this helps :)

What is the value of the fourth term in the geometric sequence

ivanzaharov [21]

Answer:

a(4) = 15/4

Step-by-step explanation:

Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.

Thus, the geometric sequence formula specific to this case is

a(n) = 30(1/:2)^(n-1).

What is the fourth term? Let n = 4,

a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,

a(4) = 15/4.

Help pleaseeeeeeeeeee

avanturin [10]

I believe your answer is going to be increasing linear. If it's doubling constantly then it's increasing so that takes out 2 options. And since it's constant, it isn't exponential, therefore you only have increasing linear left.

I hope I was able to help. Best of luck.
