Answer:
Step-by-step explanation:
take 30 degree as reference angle
using cos rule
cos 30=adjacent/hypotenuse
/2=7/y(do cross multiplication)
14
=y
14
/=y
14=y
for x
using pythagorsa theorem
H^2=P^2+B^2
14^2=X^2+(7)^2
196=X^2+147
196-147=X^2
49=X^2
=X
7=X
The answer is c because look at the relation ship with the triangle
Answer:
33
Step-by-step explanation:
Answer:
1.75a+8b
Step-by-step explanation:
Question = 0.75a + 10b + a - 2b
First collect like terms 0.75a + a + 10b - 2b
= 1.75a + 8b
what are <u>like</u><u> </u><u>terms</u> : they are terms with the same variable and the same exponent. example: 9xy and -6xy etc.......
If it's helpful ❤❤❤
THANK YOU
I'm guessing since the X makes the length of the triangle 2 more than then first one, that it does the same to the other side.
So the height would be 5 and the length 6. When you plug those into the formula A=1/2 (l×w) it makes:
A=1/2(5×6)
A=1/2 (30)
A=15 ft^2.
So the answer is H
