Answer:
7
Step-by-step explanation:
15-8=7
Answer:
it is a right
Step-by-step explanation:
the two other angles add up to 90, which makes the last angle 90 degrees, since a triangle measures a total of 180 degrees.
Answer:the number of short sleeves shirt sold is 15
the number of long sleeves shirt sold is 5
Step-by-step explanation:
Let x represent the number of short sleeves shirt sold by the student council.
Let y represent the number of long sleeves shirt sold by the student council.
The student council sells short sleeves for $5 each and long sleeve for $6 each. They were sold for a total of $105. This means that
5x + 6y = 105 - - - - - - - - - -1
The total number of shirts sold is 20. This means that
x + y = 20
Substituting x = 20 - y into equation 1, it becomes
5(20 - y) + 6y = 105
100 - 5y + 6y = 105
- 5y + 6y = 105 - 100
y = 5
x = 20 - y = 20 - 5
x = 15
Answer:
x = 24
obtuse isosceles triangle
Step-by-step explanation:
x = 24 because a triangle has to have all the angles add up to 180. So x + x +132 = 180.
180-132 = 2x
48 = 2x
x = 24
It is an isosceles because two of the angles are the same and one is different which means two of the sides are the same and one is different. (isosceles = icicle is how I remember it). Obtuse because there is an angle that is over 90 degrees.
