Answer:

Obtuse angles: 154°

Acute angles: 26°

Step-by-step explanation:

These are vertical angles. This means the angles directly across from each other are the same measure. So the two acute angles are 26°.

To find the two obtuse angles, subtract 180° and the acute angle. Both angles (acute and obtuse) together form a straight angle which is 180°

180 - 26 = 154

Simplify the expression (4-5i)(2+6i)-(3-2i) show your work.

Anastaziya [24]

The simplification of the given expression $(4-5i)(2+6i)-(3-2i)$ , we get $-30i^2+16i+5$ .

Given expression is:

$(4-5i)(2+6i)-(3-2i)$

By applying the multiplication, we get

→ $(8-10i+24i-30i^2)-(3-2i)$

By multiplying the (-) sign into the bracket, we get

→ $8-10i+24i-30i^2-3+2i$

→ $5+16i-30i^2$

By arranging the terms, we get

→ $-30i^2+16i+5$

Thus the answer above is right.
