2n + 2n = 2n squared and 17 + 21 = would be 38
so answer is : 38 + 2n squared
1+3 = 4. learn step by step!
Answer:
I am not sure but I think 69
Step-by-step explanation:
As ratio of parrot fish to clownfish is 4:3
which can be expressed as 4x:3x where x is a natural number.
as 4x = 20
so x = 5
so clownfish = 3x = 3*5 = 15
He saw 15 clownfish
Hi there!
Let's start with finding the measurement of angle A. Looking at the image, we know that the larger, outer triangle is equilateral. Therefore, we know that the inner, smaller triangle is isosceles. So, to find the measure of angle A, we need to solve this here equation:
180 = 90 + 2A
90 = 2A
A = 45
Now that we know that angle A is equal to 45 degrees, we can take the total value of the angle of the equilateral triangle and subtract the value of angle A from it to find the value of angle B.
B = 60 - 45
B = 15 degrees
Hope this helps!! :)
