Well a flat line equals 180 so you use the angle of a and try to find the other side of the angle, so you you do 180 subtracted by 125 which you get 55. Since B is parallel to the angle, the answer is 55 degrees.
Answer:
26.13716694
Step-by-step explanation:
the area of a semi cirlce is 1/2(π*r^2) so it was 14.13716694 and then you find the area of the triangle witch is H*B/2 and then add them 3 numbers together whitch is 6+6+14.13716694=26.13716694
Answer:
a+4=11b
Step-by-step explanation:
Distributive property in mathematics means to multiply the sum by a number of two or more add-ons will provide the same result that each add-on multiplies by a single number and then together add the products.
for example a( b+c) = ab+ac
Therefore, applying distributive property in asked eapression
12(2a - 6b+ 8) = 21(2a−6b+8)
24a+72b+96 = 42a-126b+168
198b=18a+72
9a +36=99b
3a+12=33b
a+4=11b
The strategy for these is to look at what these problems are telling you.
It says the y-value, so you know that this is a y = equation.
y = what?
y = 2 more than. 4 is two more than 2, right? So saying it's more than is another way of saying "y is 2 + blah blah."
So y = 2 + what? Three times the x-value. What does that mean? 3*X = 3X.
Thus we arrive at the final answer, y = 3x + 2
