Answer: -3/10
Step-by-step explanation: A positive and a negative will subtract.
1. Find the common denominator (8/10)
2. simce 8/10 is greater than 1/2 you need to add a negative to get 8/10 a lower value
3. subtract 5/10 or 1/2 from 8/10 to figure out what gives you the correct answer
Total degree in triangle is 180.
so, 180= x + 3x + (x+60)
180 = 5x +60
5x = 180-60
5x = 120
x = 24
Largest angle is 84
Middle angle is 72
Smallest angle is 24
Answer:
91 11/15
Step-by-step explanation:
23+2/15+52+8/15+16+1/15
=23+52+16+2/15+8/15+1/15
=91+11/15
