The answer is y = 14
Explanation:
AC≅CB, so the triangle is isosceles
So, m∠A = m∠B
m∠A = 50 and m∠A = m∠B, so m∠B = 2x = 50
The sum of all angles in a triangle is 180°
So:
180 = (5y + 10) + 50 + 50
180 = 5y + 10 + 100
180 = 5y + 110
-5y = 110 - 180
-5y = -70
5y = 70
y = 70/5
y = 14
Hope it helps!
Answer: n = 4
Step-by-step explanation:
Divide both sides by 3
n+2=3(6−n)
Expand
n+2=18−3n
Subtract 2 from both sides
n=18−3n−2
Simplify 18−3n−2 to −3n+16.
n=−3n+16
Add 3n to both sides
n+3n=16
Simplify n+3n to 4n
4n=16
Divide both sides by 4
n= 4/16
Simplify 16/4 to4
n=4
Answer:
4
Step-by-step explanation:
-6 + x/4 = -5
x/4 = 1
x=4
Based on the information given, the probability of getting an odd or even number will be 0.5.
<h3>
How to solve probability.</h3>
From the question given, a die is rolled once, a is the event of rolling an even number and b is the event of rolling an odd number.
A die has 6 numbers. There are 3 odd numbers and 3 even numbers.
Therefore, the probability of getting the odd or even numbers will be:
= 3/6 = 0.5
