All quadrilaterals should have 360 degrees.
Answer:
70.1 ft
Step-by-step explanation:
The cosine relation gives the ratio of the adjacent side to the hypotenuse for an acute angle in a right triangle:
Cos = Adjacent/Hypotenuse
cos(37°) = SQ/QR
Rearranging gives ...
QR = SQ/cos(37°) = (56 ft)/0.798636 = 70.1 ft
The length of QR is about 70.1 ft.
Answer:
(x-7)^2 + (y+3)^2 = 49
Step-by-step explanation:
The general equation for 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-7)^2 + (y- -3)^2 = 7^2
(x-7)^2 + (y+3)^2 = 7^2
(x-7)^2 + (y+3)^2 = 49
The first one is isosceles because it has two side lengths that are the same, C.
The missing angle measure is 35° because all of them together should add up to 180° and 105+40+35=180, A.
The possible lengths for the third triangle e are in between 7, and 17. This is because the possible side lengths are in between adding the two side lengths together, (12+5=17) and subtracting the littler side by the bigger side. (12-5=7)
