Answer:
14 m²
Step-by-step explanation:
the height of the triangle is 3 m and the base is 4 m. 3 times 4 is 12 but then you have to half that so the area of the triangle is 6 m. The area of the rectangle is 2 times 4 which is 8. 8 plus 6 is 14. So 14 is your answer.
Answer:
6
Step-by-step explanation:
since;
1/3 of 12 = 4
so,
(2/3) of x = 4
x=4(3/2)= 6
Answer:
-65
Step-by-step explanation:
use Khan academy it's very helpful
Tan x=opposite/adjacent
cot x=adjacent/opposite
so you need to inverse the fraction
tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x
so it is the second option
