1. Find angle Y. Since the interior angles of a triangle must add up to 180 deg., we have 180 - (98+24) = 58 deg.
Apply the Law of Sines to determine the lengths of sides r and t:
r 7.9 t
--------- = --------- = ---------
sin 98 sin 58 sin 24
Then r = (7.9 sin 98)/ (sin 58) = 9.22. This matches r in the 2nd choice. Determine t using the same method: t = 7.9sin 24 / sin 58.
Does your t value match that in the 2nd possible answer?
Answer:
x = 58
Step-by-step
d is parallel to m => (2x-26) ° and 90 ° are Alternate interior angles
2x - 26 = 90
2x = 90 + 26
2x = 116
x = 58

Step-by-step explanation:
Apparently you want to simplify ...
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
1/a^b = a^-b
(a^b)^c = a^(bc)
__
So the expression simplifies as ...
8 × 46 = 8 × (40 + 6) = (8 × 40) + (8 × 6) = 320 + 48 = 368
Hope this explains it.
Answer:
100
Step-by-step explanation:
You start with multiplication. -1 * -9 is 9. Then you add 1 and 9, which is 10. Lastly, you do 10 to the second power(10 * 10), which comes out as 100.
