Answer:
m∠EGC=70°
Step-by-step explanation:
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite
so
m∠EGC=(1/2)[arc EC+arc DF]
<u><em>Find the value of x</em></u>
we have
m∠EGC=(7x+7)°
arc EC=50°
arc DF=10x°
substitute and solve for x
(7x+7)°=(1/2)[50°+10x°]
14x+14=50+10x
14x-10x=50-14
4x=36
x=9
<u><em>Find the measure of angle EGC</em></u>
m∠EGC=(7x+7)°
substitute the value of x
m∠EGC=(7(9)+7)°=70°
Answer:
-2, -1/2
Step-by-step explanation:
Answer:
12cx^2-24c
-2x^3-12x^2y
Step-by-step explanation:
They shouldn't be written like that but just distribute
You basiclly just have to divide the 16 by the 4 dollars because 4 dollars os for everything but when you divide it it will give you the unit rate which is 4.
Answer:
Step-by-step explanation:
A = ½(5.5)(6.4) + ½(5.5)(5.2)
A = ½(5.5)(6.4 + 5.2)
A = ½(5.5)(11.6)
A = 31.9 in²
