Answer:

Step-by-step explanation:

answer is 98 degree because the relation between missing angle and 98 degree is alternate exterior angles and alternate exterior angles are always equal.

answer is 89 degree because the relation between missing angle and 89 degree is corresponding angles and corresponding angles are always equal.

in the 5th question

let's consider the angle there as A so angle A is 98 degree and by the relation of alternate angles the question mark (?) is 98 degree

in 6th question

by the relation of corresponding angles the question mark(?) is 89 degree

Answer: C can complete the work in 12 days.

Step-by-step explanation:

Alright, lets get started.

Given that, A and B can separately do a piece of work in 24 days and 16 days respectively.

It means, in 1 day, A can complete the part of work : $\frac{1}{24}$

It means, in 1 day, B can complete the part of work : $\frac{1}{16}$

As they both worked together for 6 days,

in 6 days, A can complete the part of work : $6*\frac{1}{24}=\frac{1}{4}$

in 6 days, B can complete the part of work : $6*\frac{1}{16}=\frac{3}{8}$

So, together they had completed the work : $\frac{1}{4}+\frac{3}{8}=\frac{5}{8}$

So remaining work will be : $1-\frac{5}{8}$

So remaining work will be : $\frac{3}{8}$

Now this remaining work is done by A and C together.

Suppose C alone can do this work in C days.

So in 3 days, A and C completed the rest work :

$3 \times(\frac{1}{24}+\frac{1}{C})=\frac{3}{8}$

$\frac{1}{24}+\frac{1}{C}=\frac{1}{8}$

$\frac{1}{C}=\frac{1}{8}-\frac{1}{24}$

$\frac{1}{C}=\frac{1}{12}$

$C=12$

Hence C can complete the work in 12 days. : Answer

Hope it will help :)

Solve for the value of x.

77julia77 [94]

Answer:

x=4

Step-by-step explanation:

Given M is the midpoint

We know that midpoint of a line divides the line into two equal parts

Therefore on equating we get

$4x + 1 = 8x - 15$

$1 + 15 = 8x - 4x$

$16 = 4x$

$x = 4$
