Answer:
cos(B) = a/c
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that ...
Cos = Adjacent/Hypotenuse
The leg adjacent to angle B is "a". The hypotenuse is "c", so the desired cosine is ...
cos(B) = adjacent/hypotenuse = a/c

Volume of the cube = a³ = (14cm)³= 2744 cm³
To find surface are, we need to find at first area of the face
A(face)=14² cm².
Cube has 6 congruent squares, so
Surface area of the cube = 6*14² cm²= 1176 cm²
Answer:
1. 64
2. 72 square feet
3. 31.5 square feet
Step-by-step explanation:
For the first one use the equation A=bh.
Plug in your values: A=12.8*5.
Solve: A=64
For the second one multiply 8*3 which gives you 24. Next multiply that by 3 to give you 72 square feet.
For the third one multiply 9 by 3.5 to get 31.5 square feet.
Answer:
-1/4
Step-by-step explanation:
Take two points on the line
(-4,-1) and (0,-2)
Using the slope formula
m = (y2-y1)/(x2-x1)
= ( -2 - -1)/( 0 - -4)
= (-2+1)/ ( 0+4)
-1/4
