<h2>c=10.35</h2><h2><a=50.87°</h2><h2><b=87.13°</h2>
Step-by-step explanation:
as we know
law of cosine
using the law of cosine
b=87.13°
Answer: B is 11 feet tall
A=x+1 since A is one more than B
C=x+1/2 since C is one half more than B
B=x since B is just B
A+B+C=34.5
x+1+x+x+1/2=34.5
3x+1.5=34.5
3x=33
x=11
B is 11 feet tall
Answer:
x = - 2
Step-by-step explanation:
Given
× = 18 = 2 × 9 = × 3²
Then
=
Since bases on both sides are equal, both 2, then equate exponents
x + 3 = 1 ( subtract 3 from both sides )
x = - 2
Then
=
and
= 3²
18 = 2 × 3²
Answer:
x=-2
Step-by-step explanation:
3(8x+12)-15x=2(3-3x)
24x+36-15x=2
(3-3x
The prime number is 13. No number under 13 can't go into it, and 13 x 2 is 26, so it is 13.
