Step-by-step explanation:
the picture isn't realistic but mathematically it's:
1) = 121°
2) = 59°
Answer:
a ≈ 21.8
Step-by-step explanation:
We require the third angle in the triangle
Subtract the sum of the 2 angles from 180
third angle = 180° - (75 + 31.8)° = 180° - 106.8° = 73.2°
Using the Sine rule, that is
= 
( cross- multiply )
a × sin75° = 22 × sin73.2° ( divide both sides by sin75° )
a = 
≈ 21.8 ( to the nearest tenth )
5 3/5 as an improper fraction is 28/5.
I hope this is helpful! :D
Answer:
=376.8 
Step-by-step explanation:
V=n
Where V is the volume , r is the radius and h is the perpendicular height .
r = 
m=6
h = 10m
n=3.14
v= 3.14 * 6*6 *
=376.8
The advantage of the graphing calculator is that you just have to find two independent equations, introduce them in the calculator and it will find the intersection point ot the two graphs.
The equations that you have to introduce are:
1) y = 2.25x + 24
2) y = 2.75x + 23
The algebraic solution, which will give you the same coordinates of the intersection point of the graphs is
2.25x + 24 = 2.75x + 23
2.75x - 2.25x = 24 - 23
0.5x = 1 => x 1 /0.5 = 2.
