Answer:
y=14
Step-by-step explanation:
Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.
plug in 25 in 2x and you would get 50°
Since the sum of a triangle is 180° you could set up an equation
Then, add 50+50=100+10=110
then you would then have
subtract 110 from 180, leaving you with 70
then divide and you would get 14
Check:
5(14)+10+50+50= 180
Answer:
B
Step-by-step explanation:
given
A = (
+
)h
multiply both sides by 2 to eliminate the fraction
2A = ( +
)h
divide both sides by the multiplier h
=
+
Subtract from both sides

=
, that is
=

Answer:
Proportion states that the two equal ratios or fractions are equal.
Use conversion:
1 m = 100 cm
As per the statement:
The actual width ( w) of a regulation soccer field is 90 meters (m), and the actual length is 120 meters (m
⇒Actual length = 120 m and Actual width = 90 m
It is also given that:
A coach has drawn a scale model of the field on a blackboard. If the longest side of his drawing is 18 cm.
⇒ Drawing length = 18 cm = 0.18 m
By definition of proportion:
Substitute the given values we have;
By cross multiply we have;
Simplify:
Divide both sides by 120 we get;
m
Or
cm
Therefore, the other side of the drawing width is 13.5 cm
