Answer:
x = 90°
y = 40°
z = 40°
Explanation (Concepts) :
A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.
Workouts:
z + 90° + 50° = 180°
z = 180° - 90° - 50°
z = 40°
=================
x + 90° = 180°
x = 180° - 90°
x = 90°
==================
50° + 90° + y = 180°
y = 180° - 90° - 50°
y = 40°
For this one a simple way that you can think of it is that 1 pound of banana is equivalent to 100, 3/4 pounds of banana is 75, 1/2 pounds of banana is 50, etc.
3 1/2 pounds of banana = 350
3/4 pounds of banana = 75
If i want to find out how many loafs of banana bread I can make if ONE loaf requires 3/4 pounds of banana, and i have 3 1/2 pounds of banana then I divide:
350 / 75 = 4.66
So, with 3 1/2 pounds of bananas you can successfully create 4 loafs of banana bread. the remaining .66 is not enough banana to make another loaf.
4.8 pounds, set it up as 4 over ten times x over 12, 4 times 12 divided by ten equals 4.8
<u>Final Answer:</u>
x = 20
<u>Step-by-step explanation:</u>
we'll be using the pythagorean theorem method, in this triangle the missing letter is a.
formula: 
a = x
b = 21
c = 29
a = 
a = 
(note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)
a = 
a = 20
x = 20
