Answer:
Step-by-step explanation:
According to the midsegment theorem, the length of each side of the formed triangle is the half the parallel side of DEF.
<u>So the perimeter is:</u>
- P = 1/2(12 + 16 + 20) = 24
The image is here, i am struggled with this problems too please help!
Because the cos theta < 0 then theta must be an obtuse angle
so a^2 + b^2 < a^2
C
Your answer would be the last option, 80 cm.
As this is a right triangle, you can use Pythagoras's Theorem, a² + b² = c², where 'c' is the hypotenuse and 'a' and 'b' are the legs, to find the missing side.
This gives us:
48² + 64² = 2,304 + 4,096 = 6,400
√6,400 = 80
So 80 is your answer.
I hope this helps!
Answer:
1900 = k
Step-by-step explanation:
38=k/50
Multiply each side by 50
50 *38 = k/50 *50
1900 = k
