GIVING BRAINLEIST Mason has four times as many stamps in his collection as
his friends Ferdinand and Leonard combined. Ferdinand
has 9 stamps in his collection. Mason has 76 stamps in
his collection. How many stamps does Leonard have in his
collection?
The equation 4(x + 9) = 76 models this situation. Which choice shows the
sequence of operations needed to solve this problem, using both arithmetic
and algebra?

Step-by-step explanation:

its 40

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
