Answer:
x=30°
y=62°
z=88°
Step-by-step explanation:
x+y+z=180
y+z=5x
so x+5x=180
6x=180
x=180/6=30
again z=y+26
so 30+y+y+26=180
2y=180-56=124
y=124/2=62
z=62+26=88
Answer:
Selling price= $58.5
Step-by-step explanation:
Giving the following information:
Guitar cost price= $45
Mark up percentage= 30%
<u>To calculate the selling price of the guitar, we need to use the following formula:</u>

area of ||g=base×height
75cm
2
=3b×b
b
2
=25
b=5cm, therefore height =5cm
3 just do division, always round down when dealing with real life objects as you cannot make more
