What is the next step
iragen [17]

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

Can someone help me out with this please? I suck at fractions
xxMikexx [17]

164 inches x \frac{1 foot}{12 inches} = \frac{41}{3}ft

147 inches x \frac{1 foot}{12 inches} = \frac{49}{4}ft

2\frac{1}{4}ft = \frac{9}{4}

Perimeter = 2L + 2w - 1doorway

                 = 2(\frac{41}{3}) + 2((\frac{49}{4}) - \frac{9}{4}

                = \frac{82}{3} + \frac{98}{4} - \frac{9}{4}

                = \frac{82}{3} + \frac{89}{4}

                 = (\frac{4}{4} )\frac{82}{3} + (\frac{3}{3} )\frac{89}{4}

                 = \frac{328}{12} + \frac{267}{12}

                 = \frac{595}{12}

                = 49\frac{7}{12}ft

******************************************************************************

b) 49\frac{7}{12}ft ÷ 8ft = 6.2

By what factor does the area change if one diagonal is doubled? Explain.
melisa1 [442]

The area of deltoid is defined by formula:

A=\dfrac{e\cdot f}{2}

Where e and f are diagonals.

If you were to double the size of either one. Let's say f. You would result with:

A=\dfrac{e\cdot2f}{2}=e\cdot f

Which means if either of diagonals double in length the area of deltoid will be twice as big as it was before.

Hope this helps.
