Answer:

119°

Step-by-step explanation:

the angles of a triangle make 180° (so does a straight line) therefore

180 (triangle) = a + c + 51

to find c:

180 (straight line) = 112 + c

c = 180 - 112

c = 68°

now we have

180 (triangle) = a + 68 + 51

to find a:

a = 180 - (68 + 51)

a = 180 - 119

a = 61°

to find b:

180 (straight line) = 61 + b

b = 180 - 61

b = 119°

Solve and graph the inequality 4x – 10 < 18.
tiny-mole [99]

9514 1404 393

Answer:

  • The graph has an open circle at 7.
  • The arrow points left.

Step-by-step explanation:

Adding 10 and dividing by 4, we have ...

  4x < 28

  x < 7

The comparison does not include the "equal to" case, so the circle at x=7 is open. Values of x less than 7 are in the solution set. Those values are found to the left of 7 on the number line.

  • The graph has an open circle at 7.
  • The arrow points left.

A triangle has side lengths of 24 in., 32 in., and 40 in. Is the triangle acute, obtuse, or right? A) right. B) obtuse. C) acute
statuscvo [17]
The answer is:  [A]:  "right [triangle]" .
________________________________________________
Explanation:
________________________________________________
Given:  Side lengths:
________________________________________________
  " <span>24 in., 32 in., and 40 in " ;  
________________________________________________
Divide each side length by "8" ; 
</span><span>
24 in. / 8 = 3 in. ; 

32 in. / 8 = 4 in. ;  and
 
40 in. / 8 = 5 in. . 
_________________________________________________
3 in . , 4, in,  5 in. ;  is a "right triangle" ; 

since:  3</span>² + 4² = 5² ;

→  9 + 16 = 25 ; 

according to the Pythagorean theorem:  " a² + b² = c² " .
