2. One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is twice the sum of the measures of the first two angles. Find the measure of each angle. [Hint: the sum of the three angles in a triangle equals 180°.] PLEASE SHOW YOUR WORK I WILL MAKE BRAINLIST PLEASE!!!!!!!
Answer:
first angle = 25 degrees
Second angle = 35 degrees
Third side = 120/degrees
Step-by-step explanation:
Let the size of the second angle be x degrees.
One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.
The measure of the third angle is twice the sum of the measures of the first two angles. This means that The third angle = 2( first angle + second angle). So the size of each angle is
First angle (x + 10) degrees
Second angle = x degrees
Third angle = 2(x + 10 + x) = (4x + 20) degrees
Sum of angles in a triangle = 180 degrees. Therefore, x + 10 + x + 4x + 20 = 180 degrees 6x + 30 = 180
6x = 180 - 30 = 150
x = 150/6 = 25 degrees
First angle = x + 10 = 25 +10 = 35
Third angle = 4x + 20 = 4 × 25 + 20
= 100+ 20 = 120 degrees
Hope this helps
Answer:25(1st angle),35(2nd angle),120(3rd angle)
Step-by-step explanation: (/ stands for divide)
180/6=30 (sum of angles/total units=value of one unit, third angle is 4 units as it is twice the sum of first two angles)
30x4=120 (value of unitxnumber of units of 3rd angle=3rd angle)
30x2=60 (value of unitxfirst angle+second angle total units=value of 1st angle+2nd angle)
(60-10)/2=25(1st angle)
25+10=35(2nd angle)
CHECK: 35+25+120=180
hope you get it :)
Unit rates
Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.
Answer the following questions about kileys trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that kiley is at rest.
In this task you will write the ratio of miles to hours for each leg of kileys trip. You will then express the ratio as a decimal number. Next you will find the unit rate in miles per hour for each leg of the trip.
1. The car ride from kileys house to the airport
2. At the airport, the walk from the car to the waiting area by the gate.
3. The leg from the waiting area to the airplanes takeoff
4. The airplane ride
5. The walk from the airport to the cab
6. The cab ride
