Answer:
see explanation
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin30° = , cos30° = , then
sin30° = = = = ( cross- multiply )
AB = 12
cos30° = = = = ( cross- multiply )
2 AC = 12 ( divide both sides by 2 )
AC = 6
Answer:x=−136
Step-by-step explanation: Step 1: Simplify both sides of the equation.
2+x=
7
8
x−15
2+x=

8
x+−15
x+2=
7
8
x−15
Step 2: Subtract 7/8x from both sides.
x+2−

x+2=−15
Step 3: Subtract 2 from both sides.

x=−17
Step 4: Multiply both sides by 8.

x)=(8)*(−17)
Answer:
23/36
Step-by-step explanation:
use BODMAS
fist add 3/4+2/3
to get 17/12
then subtract 17/12-7/9
to get 23/36
Answer:
1.5 goes in between the 0 and the first line (meaning 1) and 0.5 goes in between the left of the zero and the line before the zero
Answer:
D. 187 m²
Step-by-step explanation:
Alrighty, so this is a standard area problem, the formula for finding the area of a triangle is base x height ÷ 2 so:
34 x 11 ÷ 2 = 187
So the area of the triangle is 187 m²
hope this helps:)
