Simplify the expression 6X + 12 y + 5 + 2y + 8

1 answer:

6 0

There are two coefficients in this equatin,why because we have two variables "x and y " . Therefore the coefficients are (+6 for variable x) and (+14 for variable y) and we have only one constant...why? because we can only have one constant in a given equation.

Please help! Polygon ABCDE rotates 45° clockwise about point F to form polygon FGHIJ, shown in the figure. Find the measure of e

mario62 [17]

Answer:

mABC = 117 degrees

mBCD = 90 degrees

mDEA = 90 degrees

mCDE = 127 degrees

Step-by-step explanation:

Since ABCDE is congruent/equal to FGHIJ, then each angle corresponds with the angle in the other shape. I.E., A = F, B = G, C = H, etc. Finding the angle for ABC is finding the angle for FGH. This works only because there was no changing the places of the points individually. :)

3. The angle between two equal sides of an isosceles triangle is 52º.

Naily [24]

Answer:

a) 64° each

b) 15.78 cm

c) 51.78 cm

Step-by-step explanation:

a) (180 - 52)/2 = 64°

b) cos 64 = x/18, x = 7.89, 2x = 15.78 cm

c) 18 + 18 + 15.78 = 51.78 cm
