Answer: It looks like you are missing the question here. Most of the time in this type of questions, we are looking for the 3rd angle.
Let's assume that you need the 3rd angle.
There are 180 degrees in a triangle. We know 2 of the angles, so by subtracting them from 180 we can find the 3rd angle.
180 - 45 - 60 = 75
Angle C is 75 degrees. In the similar triangle Angle R is also 75 degrees because the corresponding angles are congruent.
Answer:
LCM (7, 18 and 21) = 126
Step-by-step explanation:
Step 1: Address input parameters & values
Intergers: 7 18 21
LCM (7, 18, 21) = ?
Step 2: Arrange the group of numbers in the horizontal form with space or comma separated format
7, 18 and 21
Step 3: Choose the divisor which divides each or most of the integers of in the group (7, 18 and 21), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if the integer is not divisible by the divisor. Repeat the same process until all the integers are brought to 1.
Step 4: Multiply the divisors to find the LCM 7, 18 and 21
7 × 3 × 6 = 21
LCM(7, 18, 21) = 126
The least common multiple for three numbers 7, 18, and 21 is 126
The photograph is said to be rectangular therefore the area of such should be the same as a rectangle which is the product of its length and width. We are given the width and the area of the photograph. We can easily calculate the length by dividing the area by the width which will yield a value of 12.04 in. This is the length.
Answer: 224 students own a school sweatshirt.
Step-by-step explanation:
40% of 560 means 60% do not have one
0.60 is 60% as a decimal
560 x 0.60 = 336 students without a sweatshirt
560 - 336 = 224
3/4 is greater than 2/5. 2/5 is .4 and 3/4 is .75
