The other angles in the isosceles triangle with an angle of 100° will be 40°
Step-by-step explanation:
Lets define an isosceles triangle first.
"An isosceles triangle is a triangle with two equal sides and two equal angles.
Given that an angle of the triangle is 100°
We know that the sum of internal angles of a triangle is 180°
The sum of remaining two angles is:
=180°-100°
=80°
As the triangle is an isosceles triangle, the two angles will be equal.
So the angles will be:

Answer:
E(t) = 5t +672 ($)
Step-by-step explanation: INCOMPLETE QUESTION
FROM GOOGLE
she earns 12 $ per hour as tutor and 7 $ per hour as waitress, this month she worked a combined of 96 hours at her two jobs
Let be t the numbers of hours Leila works as tutor this month
Answer:
If Leila worked t hours as tutor then, she worked (96 - t) hours as waitress
E(t) = 12 * t + 7 * (96-t)
E(t) = 12t + 672 - 7t
E(t) = 5t +672 ($)
