Recall that a flat-line is always 180°, so the 110° angle is just a supplementary angle, and her sibling is the angle in the triangle, check the picture below.

if you notice the tickmarks on those sides, that means they're equal, that means is an isosceles triangle, or with two equal sides, so the 70° angle is the vertex angle, and the other two angles are just two twins, 180 - 70 = 110, split that equally to the twins, and you get that, check the picture.

what's is "x"?  well, "x" is just a supplementary angle of the one inside the triangle, thus 180 - 55.

A rectangular garden is 17 feet wide. Its length is 3 feet more than twice the width. What is the area of the garden?
sleet_krkn [62]

Answer:

a = 629

Step-by-step explanation:

a = w * L

w = 17

L = 2w + 3

a = (17) * (2w + 3)

a = (17) * (2(17) + 3)

a = 17 * (34 + 3)

a = 17 * (37)

a = 629

Plz tell me how to do question 18
bagirrra123 [75]

Answer:

750kmph

Step-by-step explanation:

Average is sum of all parts divided by the number of parts.

Let Stot be average speed for total trip (800kmph).

Let S1 be speed for first quarter of trip (950kmph).

Let S2, S3, and S4 be the speeds of each of the remaining quarters respectively.

Let Sans be the average speed for the remaining three quarters of the trip (a.k.a. The Answer!).

Stot = (S1 + S2 + S3 + S4) / 4

800kmph = (950kmph + S2 + S3 + S4) / 4

3200kmph = 950kmph + S2 + S3 + S4

3200kmph - 950kmph = 2250kmph = S2 + S3 + S4

Divide both sides by 3.

2250kmph / 3 = (S2 + S3 + S4) / 3 = Sans

Sans = 750kmph
