An equilateral triangle and an isosceles triangle share a common side. what is the measure of ABC ?

erastovalidia [21]

Answer:

$\angle ABC=116^o$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of the vertex angle ∠ABD of an isosceles triangle

we know that

An isosceles triangle has two equal sides and two equal angles

In this problem

$\angle BDA=\angle BAD=62^o$ ----> the angles of the base are equals

Find the measure of the vertex angle ABD

$\angle ABD=180\°-2*62\°=56\°$ ------> the sum of the internal angles of a triangle is equal to 180 degrees

step 2

Find the measure of the angle ∠CBD in the equilateral triangle

we know that

A equilateral triangle has three equal sides and three equal angles

The measure of the internal angle in a equilateral triangle is equal to 60 degrees

$\angle CBD=60\°$

step 3

Find the measure of the angle ∠ABC

we know that

$\angle ABC=\angle ABD+\angle DBC$ ---> by addition angle postulate

substitute the values

$\angle ABC=56^o+60^o$

$\angle ABC=116^o$

7 kids on the basketball team return sick from a weekend playing games at Lakenheath High school with a virus. The aggressive vi

Lilit [14]

Answer:

It would take 6 days for 500 students to be affected.

Step-by-step explanation:

Given that:

1. Seven kids returned with the virus.

2. The aggressive virus spreads at 130% each day.

We want to find how many days until 500 students are infected by the virus.

First day:

7 students have the virus, 130% of 7 student will contract the virus again.

130% of 7 = (130/100) × 7

= 1.3 × 7 = 9.1 ≈ 9

9 new students are affected

New total affected = 7 + 9 = 16 students.

Day 2:

Affected = 1.3 × 16 = 20.8 ≈ 20

New total affected = 20 + 16 = 36

Day3

Affected = 1.3 × 36 = 46.8 ≈ 46

New total affected = 36 + 46 = 82

Day4

Affected = 1.3 × 82 = 106.6 ≈ 106

New total affected = 106 + 82 = 188

Day5

Affected = 1.3 × 188 = 244.4 ≈ 244

New total affected = 244 + 188 = 432

Day6

Affected = 1.3 × 432 = 561.6 ≈ 561

New total affected = 561 + 432 = 993

Therefore, it would take 6 days for 500 students to be affected.
