Answer:
D. zero product property
Step-by-step explanation:
Base on the Zero Product Property, if the product of factors gives us 0, either of the factors or both would equal 0.
Thus,
xy = 0, therefore,
x = 0 or y = 0
Therefore, the property that is represented by the calculation given in the photo is Zero Product Property.

Answer: Angle 1 = 27
Angle 1 = 63
Remember: complementary angles always add up to 90 degrees.
Set up your equation.
3x + 7x = 90 Combine like terms
10x = 90 Divide by 10 to both sides
x = 9 Answer!
Substitute in (9) for x to find the measurements of the two angles.
Angle 1: 3x
3(9)
27
Angle 2: 7x
7(9)
63
You can also check your work.
27 + 63 = 90
∠S = 360° - ∠T - ∠Q - ∠R
∠T = 90°
∠Q = 128°
∠R = 57°
∠S = 360° - 90° - 128° - 57° = 85°
Answer: ∠S = 85°.
Answer:
The roof does form a right triangle.
Step-by-step explanation:
If it is a right triangle then it will obey the Pythagoras Theorem.
Now (√186)^2 = (√93)^2 + (√93)^2
186 = 93 + 93 = 186
So it obeys the theorem and is therefore a right triangle.
