Answer:
x = 60°
Step-by-step explanation:
We know that ∠H is 30° and we know that ∠J is 90° thanks to the red box. The sum of the angles of a triangle is 180°, so we can use this to solve for x.
x + 30 + 90 = 180
x + 120 = 180
x = 60
Therefore, it is 60°.
Answer:
The equation to find the number of students in the
the band will be: 2x - 8= 54
Step-by-step explanation:
Let the number of members in the chorus = x
so the double number of members in the chorus will be = 2x
As Total members in the chorus = 54
As there are 8 fewer than double the number of students in the chorus than in the band. i.e. 2x - 8
Therefore, the equation to find the number of students in the
the band will be: 2x - 8= 54
Answer:
If the bolt is .52, it is between .517 and .583, so it can go in the package.
Step-by-step explanation:
The first step is to determine what the error amount is
6% of .55
.06*.55 =.033
The bolt must be within .033 of .55
.55 - .033 = .517
.55 + .033 = .583
The bolt must be between .517 and .583 inches
If the bolt is .52, it is between .517 and .583, so it can go in the package.
