Answer:
70° is your measurement for ∠t.
Step-by-step explanation:
Note that a straight line has an angle of 180°
It is given to us that ∠r and ∠t = 180°, and that m∠r = 110°
Plug in 110 for ∠r
110 + ∠t = 180
Isolate ∠t. Note the equal sign, what you do to one side, you do to the other. Subtract 110 from both sides
110 (-110) + ∠t = 180 (-110)
∠t = 180 - 110
∠t = 70
70° is your measurement for ∠t.

Answer:
866.64
Step-by-step explanation:
40/2 = 20
A = πr²
3.14*20² = 1256
52/2 = 26
3.14*26² = 2122.64
2122.64 - 1256 = 866.64
Answer:
∠TUS I'm pretty sure because t and u make a right angle
Here's how you simplify those. The rule for raising an exponent to an exponent is that you multiply them. The rule for dividing exponents with the same base is that you subtract the denomonator from the numerator. So let's simplify the first one, which is actually the most confusing.

Multiplying the exponents you get:

Subtracting the denominator from the numerator between the common base of p you get this:

Doing that math gives you

which equals

which is

, or the third one down.
The next one:

simplifies to:

and subtracting the power of the denominator from the power of the numerator gives you:

, which is the last choice.

simplifies to:

which simplifies very nicely to:

, which is the first choice. The other one is found by process of elimination!
