There's no dividing the angle in half in the trig triangle area formula.
Area = (1/2) ab sin C = (1/2) ac sin B = (1/2) bc sin A
Answer: check second and third choices
Answer:
D
Step-by-step explanation:
D)
13% of x is 2600
13% = 13/100
⇒ (13/100)x = 2600
⇒ 13/100 = 2600/x
FYI A) gives the same value of x as D)
Answer:
CNBD
Step-by-step explanation:
From the diagram, we can see that:

Then by Alternate Interior Angles:

From vertical angles, we also know that:

This is all we can gather from the given image. Knowing only three pairs of angles cannot prove congruence, as proving congruence requires at least one side.
Congruence cannot be determined.
The answer is 7!
The number In front of the variable is always the coefficient.
Answer:
x=18
Step-by-step explanation:
180=62+(7x-8)
solve
x=18
