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
Answer:
0.04 is the most common correct answer for the the formula
P=2L+2W
P-2W=2L
P/2-W=L
L=P/2-W
Answer:
for number 4 the answer is 32 in (please read below)
Step-by-step explanation:
I will do one of them for now... how about number 4.
Similar triangles means we are going to setup a proportion:
Small triangle Big Triangle
Corresponding 12 15
Corresponding x 40
So the proportion is 12/x=15/40
cross multiply
12(40)=15(x)
Divide both sides by 15
giving x=12(40)/15=32
Try number 1... And I will check it for you (just post as a new question-I will be looking for it)
