Answer:
<h2>V = 420 mm³</h2>
Step-by-step explanation:
The formula of a volume of a rectangular prism:
l - length
w - width
h - height
We have <em>l = 10.4mm</em>, <em>w = 5mm</em>, <em>h = 8mm</em>.
Substitute:
If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
Answer:
7
Step-by-step explanation:
3(y+5)=36
divide both sides by 3
y+5=12
minus 5
y=7
