Answer:
A = bh (the last one)
Step-by-step explanation:
To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply. The base and height of a parallelogram must be perpendicular.
No that wouldn't work.
e.g 1/2 + 1/2 would become 2/4 (which is equivalent to 1/2) if you just added the numbers, which can't be right.
You need to find equivalent fractions so that each fraction has the same number on the bottom (denominator) and then add ( or take away) the top numbers.
1/2 + 1/2 has same number on bottom, so just add top numbers to get 2/2 =1
so 1/4 + 1/2 has diff nos on bottom, so change 1/2 to 2/4.
1/4 + 2/4 = 3/4
2/3 - 1/4 = 8/12 - 3/12 = 5/12
You may need to ask your teacher about equivalent fractions.

Step-by-step explanation:
Harold was wrong, he multiplied incorrectly 7 times 4 is 28.
Using relations in a right triangle, it is found that the length of AC is of 6.43 inches.
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
In this problem, the length of side AC is b, which is opposite to the angle of 40º, while the hypotenuse is of 10 in, hence:
