Answer:
(3)
and 
(4) 
Step-by-step explanation:
Question 3
Required
Solve for x and y
We have:
--- angle on a straight line
Collect like terms


Solve for x


Also:
---- opposite angles
So, we have:



Divide by 2


Question 4:
Required
Solve for x
We have:
---- angle at right-angled

Divide by 16

Answer:
<h2>Side YZ is 8 units long.</h2>
Step-by-step explanation:
We can deduct form the graph that segment WO is a radius of the circle and XY is its diameters.
By given, we know that
, which means
, by radius definition.
An important characteristic of tangents about circles is that the tangent is always is perpendicular to the radius, that means
and
is a right triangle, that means we can use Pythagorean's Theorem to find the side YZ.

Where
is the hypothenuse and
,
are legs of the triangle.
Replacing all given values, we have

However, by sum of segments, we have
, where
and 

Therefore, side YZ is 8 units long.
Jones has 3/4 total fertilizer. He wants to use 1/8 each scoop to use all of the fertilizer.
We need to make these into proportions to understand the amount of each fraction easier. 1/8 = 0.125, and 3/4 = 0.750
To do this the quick way, divide 0.750 by 0.125
0.750/0.125 = 6.
He will have to use the measuring cup 6 times.
Hope this helps!
