Answer: 45°
Step-by-step explanation:
Given that :
∠A=5x−15°---(1)
∠B=2x+21°----(2)
Equating
∠A = ∠B
(5x−15)° = (2x+21)°
5x - 15 = 2x + 21
Collecting like terms
5x - 2x = 21 + 15
3x = 36
x = 12
Substitute x = 12 in either angle A or B since both are congruent
∠A=(5x−15)°
∠A = (5(12) - 15)°
∠A = (60 - 15)°
∠A = 45°
∠A = ∠B = 45°
For example, if your fraction was 1 1/2, you would graph it on the x axis halfway between 1 and 2
A+b=45
a>b
a=b+7
→
b+7+b=45
2b+7=45
2b=38
b=19
a=19+7=26
Answer:
The answer to question 3 is B.
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
4 ÷ 8/12
Change the sign to multiplication by switching the denominator with the numerator
=4 x 12/8
8 is divisible by 4 which gives you 2 therefore;
= 12/2
= 6
Hope this helps :)
