i think you do it by like
12squared - 1.5 squared = A Squared
you do this to get the height
so
144- 2.25 = 141.75 then you square root it which equals 11.90
11.90×3÷2 = 17.85
17.85×6= 107. 15
im not sure
Answer:
104 + 3(90.50)
Step-by-step explanation:
Always do what's inside the parenthesis first.
PEMDAS
Use the sine function here.
x
--- = sin 20 degrees = 0.349, so x = 10(0.349) = 3.42
10
There is a rule, that says:
sum of angle measures is always equal to 180 degrees.
thats why:
1) total degrees =180 = 45 + 90 + x
so x = 180 - 45 - 90= 45 degrees
the answer is that you can have unlimited number of triangles with those measures (different lengths of sided of triangles, but third angle has to have 45 degrees)
2) 180 = 67 + 27 + x
x = 180 - 67 - 27 = 86 degrees
Answer:
3/4
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal.
