Answer:
x=9
Step-by-step explanation:
a scale drawing means all the sides are multiplied by the same amount. to find this amount, you can divide the larger side by the bigger side by the smaller side.
15/5 = 3
12/4 = 3
therefore the scale factor is 3. to get the value of x, multiply the value of the third side by 3.
3*3=9
x=9
Let the angle be x
complement 90-x
so the equation will be
3x = 90-x-14
3x+x = 90-14
4x = 76
x=76/4= 19
90-x= 90-19 =71
Answer:
x=2.66
Step-by-step explanation:
6x=60-10y-8z
x=(60-10*2-8*3)÷6
x=(60-20-24)/6=16/6=2.66
Answer:
15
Step-by-step explanation:
90 - 30 = 60
60 - 45 = 15
