THEOREM:
- Angle sum property —: The sum of interior angles of a triangle is 180°.
ANSWER:
Let the missing angle be x.
By angle sum property,
- ∠x + 20° + 80° = 180°
- ∠x + 100 = 180°
- ∠x = 180° – 100°
- ∠x = 80°
So, <u>Correct choice</u> - [C] 80°.
Answer:
336 cubic inches
Step-by-step explanation:
Multiply length by width by height for volume.
3x+4y=12
4y=12-3x
y=(12-3x)/4 <---------- This is f(x)
---------------------
3x+4y=12
3x=12-4y
x=(12-4y)/3
Therefore:
f⁻¹(x)=(12-4x)/3
=[4(3-x)]/3
Answer:
5/6 miles
Step-by-step explanation:
Matthews travels 2.5 miles → this is 3 times the distance that Jennifer travels
Jennifer travels 2.5 / 3 miles = 5/6 miles
because,
2.5 = 2 and 1/2 = 5/2
(5/2) ÷ 3 = (5/2) *(1/3) = 5*1/ 2*3 = 5/6
