Answer:
8, 40 , 50
Step-by-step explanation:
the measure of A is 90°
so 5x + 7x - 6 = 90
now.. to find the x
5x + 7x - 6 = 90
5x + 7x = 90 + 6
12x = 96
x = 96/12
x = 8
so the measure of angle A1 is (5*8) = 40
the measure of angle A2 is (7*8-6) = 50
finaly the angle A is (50+40) = 90
Corresponding sides have the same ratio, so
x/15 = 12/(12+8) = 3/5
x = 15*3/5
x = 9
Answer:
£1920
Step-by-step explanation:
The amount she spent in 2016 is 20% less than 2017. 20% less than is the same as 80% of the amount she spent in 2017. So, to find how much she spent in 2016, multiply 2400 by 0.80 (the decimal form of 80%):
2400 * 0.8 = 1920
Emily spent £1920 on holiday in 2016.
I hope this helps :)
Answer:
5 1/3 or 5.33333333333333333333333333333333333333333333333333333
Step-by-step explanation:
to find the scale factor, you must divide the two equal sides.

which equals
or 0.75
Now, the way to get the value of x is to divide 4 by 3/4 0r 0.75
Which equals
5.333 repeating or 5 1/3
