Answer:
measure of angle ABC is 6 degree.
Step-by-step explanation:
After you found x, you'll plug it in the equation of the angle it's asking for.
Measure of angle ABD, and you know measure of angle ABC = 4x-1.
4(1)-1 = 4-1 = 3
Measure of angle CBD = 2x+1.
2(1) +1 = 3
Measure of angle ABC is ABD + CBD
3 + 3 = 6
S = 10x^2
S/10 = x^2
+or-sqrt(S/10) = x
+or- sqrt(S10)/10 = x
so
_inverse = +or-sqrt(10x)/10
