Outer: 2i

Inner: -3i*2 = -6i

Last: -3i*i = -3i^2 = -3(-1) = 3

Add them together

Which angle in the isosceles triangles is the biggest?
IgorC [24]

Answer:

Since the two base angles are congruent (same measure), they are each 70°. If we are given a base angle of say 45°, we know the base angles are congruent (same measure) and the interior angles of any triangle always add to 180°.

givi [52]

Step-by-step explanation:

Geometric series.

Month 3.

      100(1+\frac{0.02}{12})^2 + 100(1+\frac{0.02}{12})+100

Month 4.

100( 1 + \frac{0.02}{12})^3 + 100( 1 + \frac{0.02}{12})^2+100(1+\frac{0.02}{12})+100

Month 5.

100(1 + \frac{0.02}{12})^4 + 100(1 + \frac{0.02}{12})^3 + 100(1 + \frac{0.02}{12})^2 +100( 1 + \frac{0.02}{12}) + 100

Can someone pls help with these geometry questions, it’s urgent.
Phantasy [73]

Answer:

6. x + x + 14 = 90

   2x + 14 = 90

   2x = 76

   x = 38

angle b = 38 + 14 = 52°

7. angles on a straight line add up to 180°

   x + x - 32 = 180

   2x = 212

    x = 106°

angle d = 106 - 32 = 74°

8. vertically opposite angles are equal

   7x - 80 = 3x

    -80 = -4x

     20 = x

angle 1 = 7(20) - 80 = 60°

angle 2 = 3(20) = 60°

You have 2\3 of a pizza left from yesterday. You divide it into 4 equal pieces. What fraction of the pizza is each piece?​
romanna [79]
<h3>Answer:  1/6</h3>

====================================================

Explanation:

Let's say for example this pizza had 6 slices to start with. Two-thirds of this is (2/3)*12 = 4 slices. So you have 4 slices left over from yesterday. Then let's say you hand one slice to each of your four friends. Each friend would have 1/6 of the original pizza.
