Answer:
x = 9
Step-by-step explanation:
angle 1 plus angle 2 equals 90 because they are complementary. combining like terms gives you 8x + 18 = 90. then you get 8x = 72, which means that x equals 9
It takes about 4 days for the temperature to decrease by 9°F.
An equation is an expression that shows the relationship between two or more variables or numbers.
Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):
-1 1/2 * x = -9
-1.5x = - 9
x = 4 days
It takes about 4 days for the temperature to decrease by 9°F.
The vlaue of z is 27°
Step-by-step explanation:
Given,
The angle is 63°
To find the value of z
We know that the diagonals of rhombus perpendicularly bisect each other.
Again,
z+63°+90° = 180° [ sum of all the triangle is 180°]
or, z = 27°
