Answer:
50
Step-by-step explanation:
Step 1: Recognizing that we have an isosceles triangle
This is an isosceles triangle because it has two congruent sides(two sides with a length of 7). The angles across from the congruent sides are also congruent, so the angle without a label measures x∘
x, degrees:
Hint #22 / 4
Step 2: Writing an equation
The three angles in a triangle add up to 180 180 ∘
180, degrees. We can write this as an equation:
x + x + 80 = 180∘
+x ∘
+80 ∘
=180 ∘
x, degrees, plus, x, degrees, plus, 80, degrees, equals, 180, degrees
Hint #33 / 4
Step 3: Solving for x
x+x+80
2x+80
2x+80−80
2x
2
2x
x
=180
=180 Simplify the left-hand side
=180−80 Subtract 80 from each side
=100
=
2
100
Divide each side by 2
=50

The answer
x = 50
Answer: The answer is B.
Step-by-step explanation: The scale on the y-axis could be changed to 100–120.
We are given a rain gutter made from folding a 12 inch wide aluminum sheet to an angle theta. The area of the opening is expressed as A(Θ) = 16 sin Θ (cos Θ + 1) where <span>Θ = 60°. we can just substitute directly the angle in degrees mode in the calculator and the answer is equal to 20.78 inches2.</span>
We will first multiply -4 and 2, that is the total of -8. Then with the -8, we will multiply that with -9, which is 72.
A negative times a negative is a positive.
A positive times a negative is a negative. :)
Please mark as brainiest!
Answer:
1. isosceles and acute
2. Scalene and acute
3. Equilateral and equiangular
4. Right (and isosceles ?)
(not sure ab isosceles for the last one but everything else is fine)
:)
