Answer:
y = 8
x = 8√5
z = 4√5
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (y), x is a projection (16), and y is the other projection (4):
y 4
---- = -----
16 y
Cross multiply:
y² = 16 (4)
y² = 64
√y² = √64
y = 8
To find x and z, use the Pythagorean Theorem:
16² + y² = x²
256 + 8² = x²
256 + 64 = x²
320 = x²
√320 = √x²
√64√5 = √x²
8√5 = x
x = 8√5
4² + y² = z²
16 + 64 = z²
80 = z²
√80 = √z²
√16√5 = √z²
4√5 = z
z = 4√5
Below zero that means negative
So answer is -21
If a triangle equals 180, than what you want to do is add all of the numbers together. 33+21+28= 82.
After that what you want to do is subtract that by the total of the triangle "180"
180-82=98.
I believe 98 is the answer
You have to find the common denominator*

I completed #1 for you. Each image shows one of the steps.
<em>Follow the exact same steps to complete #2 - #5</em>
#6 asks for a double angle.
Add an extra item to step 3: Draw an arc from vertex through the line
--> then draw another arc from B' to the other side of your line (away from the dot) and label that intersection as B''. Use the measure of the vertex to B'' for the remaining steps.
<em>If you need step-by-step images, you will need to post #6 separately as I can only upload 5 images per question.</em>
