Answer:
perimeter is 46
Step-by-step explanation:
Sq(BT) = sq(AT) + Sq(AB)
Sq(17) = Sq(8) + Sq(AB)
So AB = 15
So perimeter of ABCT is 15 + 15 + 8 + 8 = 46
1/3 of 120 is 40
1/4 of 120 is 30
therefore, 10 more scouts in the first group elected to go on the trip
Answer:
vertex angle = 180° - 2x
Step-by-step explanation:
Since, the measure of each base angle of an isosceles triangle is represented by x.
So, by interior angle sum postulate of a triangle, we have:
x + x + vertex angle = 180°
2x + vertex angle = 180°
vertex angle = 180° - 2x
So, the vertex angle is represented by (180° - 2x).
The overall total of the group of golfers is 3 over par or (+3).
In order to find this, we just need to add the numbers together.
2 - 3 + 5 + 0 - 1 = 3
