I've done this before try using the a squared plus b squared =c squared formula nvm I do t know what I'm talking about
Answer:
x=3
Step-by-step explanation:
2(x+1)=x+5
Use the distributive property to multiply 2 by x+1.
2x+2=x+5
Subtract x from both sides.
2x+2−x=5
Combine 2x and −x to get x.
x+2=5
Subtract 2 from both sides.
x=5−2
Subtract 2 from 5 to get 3.
x=3
Answer:
3y - 10
———
2
Step-by-step explanation:
We know that
if angle A=45°
then
angle C is also 45°
therefore
if BC=6
AB is also 6
<span>applying the Pythagorean theorem
</span>AC²=AB²+BC²--------> AC²=6²+6²------> AC²=72------> AC=6√2
cos 45=6/(6√2)--------> cos 45=1/√2
the answer is the option B
cos 45=1/√2
What is the question to that?
