HELPPPPPPPPPPPPPPP RATE 5 STARSS

Stels [109]

Answer:

13. c,

14. a.

Step-by-step explanation:

13. The length of a side PQ with coordinates of

P as (x,y) and Q as (w,z)

is: $\sqrt{(x-w)^{2} +(y-z)^{2} }$

so, the length of the side AB =

$\sqrt{(5-5)^{2}+(-2+7)^{2} } =\sqrt{0^{2}+5^{2} } =5$

the length of side BC =

$\sqrt{(5-1)^{2}+(-7+2)^{2} } =\sqrt{(4)^{2}+(-5)^{2} } =\sqrt{4^{2}+5^{2} }$

the length of side AC=

$\sqrt{(5-1)^{2} +(-2+2)^{2} } =\sqrt{4^{2} } =4$

now, the easiest one will be when the vertices are on the coordinate axes.

so, option c will be the most appropriate one.

14. If u see the figure clearly, the lines l and FH are parallel.

the parallel postulate, i.e, the alternate interior angles will always be congruent.

here, the alternate interior angles are angle1 and angle4.

therefore to prove this step, he used parallel postulate as a reason.

so, the correct option is "a"

Pls help me with this question

erma4kov [3.2K]

As in this figure two sides of triangle are equal so angle A=B because angle opposite to equal sides are equal so

60+x+x= 180
60+2x=180
2x= 180-60
2x=120
x=120/2
x=60
Therefore B,C is 60

Solve for s. 1/2 s = 7/2. A 1/7. B 2/7. C 3. D 7.

fenix001 [56]

Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

$\frac{1}{2} s = \frac{7}{2} \\ \\\frac{(\frac{1}{2}s)}{\frac{1}{2}} = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{7}{2} * \frac{2}{1} \\ \\\\s = 7$

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
