See attachment for illustration
Required
Find x
To do this, we have:
--- similar triangles
So, we have the following equivalent ratios

Where:

Substitute these in the above equation


Express as fraction


Cross multiply

Open bracket

Rewrite as:

Expand

Factorize

Factor out x + 284

Split

Solve for x

x can't be negative;
So:

Sin ( theta ) = opposite / hypotenuse
sin ( 37° ) = 13 / x
Answer:
r = 35.18 mm
Step-by-step explanation:
We have,
The diameter of a reamed hole is 70.36 mm.
It is required to find the radius required to draw the hole.
The relation between diameter and radius is given by :
D = 2r
r is radius setting

So, the radius setting used to draw the hole is 35.18 mm.
The answer is 441 by multiplying the number of red cars with 7
Answer:
d = 5
Step-by-step explanation:
Pythagorean Theorem
a^2 = b^2 = c^2
3^2 + 4^2 = 9 + 16 = 25
sqrt.25 = 5
