The rules tell me to add the exponents. But I when I started algebra, I had trouble keeping the rules straight, so I just thought about what exponents mean. The " a6 " means "six copies of a multiplied together", and the " a5 " means "five copies of a multiplied together". So if I multiply those two expressions together, I will get eleven copies of a multiplied together. That is:
The answer would be 126 square inches because you have to break up the figures and figure out the area for each one so for the rectangle the area would be 75 because of the formula length times width then for the square it would be 16 because the formula is the side (squared) then for the last one the parallelogram it would be 35 because of the formula base times height. Hope this helped :)
Answer:
a = √11 and b = 6
Step-by-step explanation:
Refer to attached picture for reference
for an right triangle with angle θ
we are given
cos θ = 5/6 = length of adjacent side / length of hypotenuse
hence
adjacent length = 5 units
hypotenuse length = 6 units
the missing side is the "opposite" length which we can find with the Pythagorean equation. in our case:
hypotenuse ² = adjacent ² + opposite² (rearrange)
opposite ² = hypotenuse ² - adjacent ²
opposite ² = 6² - 5²
opposite = √ (6²-5²) = √11
sin θ = opposite length / hypotenuse (substitute values above)
sin θ = √11 / 6
hence a = √11 and b = 6
Answer:
1st one
Step-by-step explanation:
I have answered ur question
They are the same angle. congruent means that they are all in the same spot were the numbers line up and these ones do so the answer is that they are all the same angle.
