Answer:

13m + 8

Step-by-step explanation:

Distribute

(20<em>m</em> + 3) - 1(7<em>m</em> - 5)

(20<em>m</em> + 3) - 7<em>m</em> + 5

Eliminate redundant parentheses

(20<em>m</em> + 3) - 7<em>m </em>+ 5

20<em>m </em>+  3 - 7<em>m </em>+ 5

Add the Numbers

20<em>m </em>+  3 - 7<em>m </em>+ 5

20<em>m </em>+ 8 - 7<em>m</em>

Combine Like Terms

20<em>m </em>+ 8 - 7<em>m</em>

13<em>m </em>+ 8

Solution

13<em>m</em> + 8

How do you find x in this question?
ivanzaharov [21]

Answer:

  x = 70°

Step-by-step explanation:

The relevant relations are ...

  • base angles of an isosceles triangle are congruent
  • consecutive interior angles where parallel lines meet a transversal are supplementary

__

Triangle OBQ is isosceles, so angle OQB = 40°. Triangle OPQ is isosceles, so angle OQP is x. The sum of angles OQB and OQP is angle BQP, which is supplementary to angle OPQ. That is, ...

  (40° +x) +x = 180°

  2x = 140° . . . . . . subtract 40°

  x = 70° . . . . . . divide by 2

_____

There are many ways to find x. The one shown here is just one of them. In general, right triangles, isosceles triangles, symmetry, inscribed angles can all be used to write relations involving the known angles and x.
