Start with the given 4x + 1 = 6x - 2.

Combining like terms, we get 3 = 2x, from which we later get x = 3/2.

Where the question mark appears, write, "Reverse the order of 3/2 = x to obtain x = 3/2."

<h3>Answer: 85 units ^2</h3>

Step-by-step explanation:

Using the equation $a^{2} + b^{2} = c^{2}$

Find the measure of ∠EGC. Circle A with chords EF and CD that intersect at point G, the measure of arc EC is 50 degrees, the mea

miv72 [106K]

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

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°
