Answer:
The length of QR is approximately 18.3 cm
Step-by-step explanation:
The given parameters are;
The length of the side PR = 23 cm
The length of the side PQ = 22 cm
The measure of the angle QPR = 48°
By cosine rule, we have;
Plugging in the values gives;
The length of QR ≈ 18.3 cm
13x + 1 = 11x + 8
First, subtract 1 from both sides. / Your problem should look like: 13x = 11x + 8 - 1
Second, simplify 11x + 8 - 1 to 11x + 7. / Your problem should look like: 13x = 11x + 7
Third, subtract 11x from both sides. / Your problem should look like: 13x - 11x = 7
Fourth, simplify 13x - 11x to 2x. / Your problem should look like: 2x = 7
Fifth, divide both sides by 2. / Your problem should look like: x =
Answer:
x = Answer in decimal form: 3.5
A full rotation is 360 degrees, divide 360 by the rotation given in the problem:
360 / 120 = 3
A triangle has 3 inside angles, so the answer would be an equilateral triangle.
Using the distance formula you get 6,8,10
2^3 is 2*2*2 which is 8.
Hope this helps!
