Answer:
The measure of the vertex angle of the next isosceles triangle is 10°
Step-by-step explanation:
The given information are;
The first isosceles triangle; Base angles = 89°, vertex angle = 2°
The second isosceles triangle; Base angles = 88°, vertex angle = 4°
The third isosceles triangle; Base angles = 87°, vertex angle = 6°
The fourth isosceles triangle; Base angles = 86°, vertex angle = 8°
The vertices of the isosceles triangles form a arithmetic projection, with a common difference of 2°
Therefore, the vertex for next isosceles triangle = 8° + 2° = 10°
The base angles are derived from the sum of interior angles of a triangle which is 180°
Which gives;
2 × Base angles + Vertex angle = 180°
2 × Base angles + 10° = 180°
2 × Base angles = 180° - 10° = 170°
Base angles = 170°/2 = 85°
Base angles of the fifth isosceles triangle = 85°
From which we have;
The fifth isosceles triangle; Base angles = 85°, vertex angle = 10°
The measure of the vertex angle of the next (fifth) isosceles triangle = 10°
first you will distribute the 5 to(3+t)
So it will be 3t+15+5t-2t-4
then you will add 3t and 5t and -2t together
So you get 6t+15-4
Lastly you will do 15-4
So you get 6t+11
That's the answer 6t+11

Answer:
Brianna is right. The quotient is in the hundreds place ,because the first digit is 2 spaces to the left from the comma/period ,thus we know it's a hundred
