Because supplementary angles means mA + mB = 180.
Then subtract 80 from 180 which will get you 100.
So B = 100

Tom is applying for a visa.
alexdok [17]

Answer:

£210

Step-by-step explanation:

Given that :

Visa cost = £2300

7% charge of visa price = (0.07 * £2300) = £161

Total cost = £(161 + 2300) = £2461

Amount to be saved per month = £2461 / 12 = £205.08333

= £210 (nearest £10)

Find the measures of the angles of an isosceles triangle with a vertex angle of 42 degrees
I am Lyosha [343]

Answer:

69°, 69°, and 42°

Step-by-step explanation:

Isosceles triangles have three angles -- one vertex angle and two base angles.

The <u>base angles have the same measure</u> and the vertex angle has a different measure.

<u>Remember all triangles' interior angles sum to 180°.</u>

If the vertex angle is 42°, then the two base angles combined are:

180° - 42° = 138°

Since the base angles are the same, <u>each base angle is:</u>

138° ÷ 2 = 69°

Therefore the angles in the triangle measure 69°, 69°, and 42°.
