Answer:
Step-by-step explanation:
<u>Use trigonometry (shown in image below) to find the 3 side-lengths:</u>
- The side opposite of θ =
- The base side adjacent to θ = 11
- The hypotenuse = 12
<u>According to right triangle trigonometry:</u>
cos θ =
<u>Substitute in the values:</u>
cos θ =
Answer:
A
Step-by-step explanation:
You don't know whether they're all 90 degrees because we don't know about AB and CD.
Answer:
i would say no
Step-by-step explanation:
i would say no because quadrilateral FGIH is equal to 120 and quadrilateral SRTQ is equal to 134 and also their areas are indifferent FGIH's being 875 and SRTQ's being 1120
please let me know if this was wrong
hope this helps :) have a nice day !!
Answer:
x = -1
Step-by-step explanation:
Expand 2(x +5 ): 2x +10
Expand -2(x - 9) - 15: -2x + 3
Subtract 10 from both sides
Simplify it
Add 2x to both sides
Simplify it
Divide both sides by 7
Simplify it again...it will be x = -1

Answer:
3 1/3
Step-by-step explanation:
Multiply both sides by the reciprocal of the coefficient of c.
(5/2c)(2/5) = (8 1/3)(2/5)
c = (25/3)(2/5) = 50/(3·5) = 10/3
c = 10/3 = 3 1/3
