Multiply each side by p, so
kp = ar
Divide each side by a, so
kp/a = r
The answer is the third option
Answer:
Value of x: 72, first option
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees. In order to find x, one of the angles, add the other two angle measures subtracted from the sum of angles (180) as such:
180 - (51 + 57) =
180 - 108 =
x - 72 degrees
We use them to show if postulated and theorems are correct
Answer:
63.5
Step-by-step explanation:
The diagonals of a rhombus bisect opposite angles.
The longer diagonal bisects the 42° angle
The larger angle of the rhombus is 180 - 42 = 138
Let x = the length of the longer diagonal
You know two sides and the included angle of a triangle.
Using the law of cosines we get

x^2 = 34^2 + 34^2 - 2(34)(34) cos 138
= 1156 + 1156 - 2312 c0s 138
= 4030.1508...
x = sq rt 4030.1508...
= 63.5
65 is the answer. Solve the first equation and then plug in.
