∠EHF = 132°
Step-by-step explanation:
Both angles lie on a straight line.
=====================
Then ∠EHF :
Answer:
The center is (0,0) and the radius is 3
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2+(y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x-0)^2+(y-0)^2 = 3^2
The center is (0,0) and the radius is 3
The sup is 20 cm in total in square it is route 20 which is 10x2 so if its 1.50 dhs per sqm it will be 3 x 10 which is 30 dhs
So 30 x 4 is 120 please mark as brainliest
Answer: 18x^4 - 5x^3 + x^2 - 4
Step-by-step explanation:
We need to add like terms.
-10 and 6 are like terms
-10 + 6 = - 4
-3x^3 and -2^3 are like terms
-3x^3 + -2^3 = -5x^3
There are no other like terms.
18x^4 - 5x^3 + x^2 - 4
