You multiply -21 by 14 to find x, and that would be -21 x 14 = -294, and that is your answer.
Answer:
Step-by-step explanation:
Answer:
Your answer is 50 degrees.
Step-by-step explanation:
An isosceles triangles base angles are equal.
A triangle's angles add up to be 180 degrees.
65+65+x = 180
130+x = 180
x = 50
Responda:
48,5
Explicação passo a passo:
Dado que:
Custo total de bolsa e sandália = 74,00
Deixei :
Custo da sandália = x
Custo da bolsa = x - 23
Preço da sandália:
x + (x - 23) = 74
x + x - 23 = 74
2x - 23 = 74
2x = 74 + 23
2x = 97
x = 97/2
x = 48,5
Portanto, custo da sandália, x = 48,5
The measure of a central angle is equal to measure of a minor arc. That makes m<GEH=17x+12. By the Vertical Angles Theorem, m<GEH and m<IEF are equal to each other (m<GEH=17x+12=m<IEF). By the same theorem, m<FEG and m<IEH are also equal (m<FEG=8x-7=m<IEH). The angles in a circle must all add up to 360 degrees, 2(17x+12)+2(8x-7)=360. Solve for x, then plug x into the equation for m<IEF.
Hope this helps!
