Yes, you can put parenthesis inside of parenthesis.
Answer:
Step-by-step explanation:
take 45 degree as reference angle
using sin rule
sin 45=opposite/hypotenuse
1/
=x/26
x=26/
x=13
x=18.4
Answer:
x = -22
Step-by-step explanation:
2(5– x)3 – 11 = 151
(10 - 2x)3 - 11 = 151
30 - 6x = 162
-6x = 132
x = -22
In the smaller triangle, let
be the length of the smallest leg. Then the smallest leg in the larger triangle is
.
Within the scope of the smaller triangle, we have
such that

Then within the larger the triangle, we would have

Now we can solve for
:


Answer:
Explain how subtracting 4/5 - 3/5 involves subtracting 4 and 3
Step-by-step explanation:

A. 85 km
B. 115 km
C. 185 km
D. 215 km
Apparently, the answer is B.) 115 km, but I need a solution.
