Triangle- interior angles .
me !

In  ΔPQR,  x = 25  , ∠P  = 45° and  ∠R  =  90°

Step-by-step explanation:

Here, In ΔPQR,

∠P = x°,  ∠Q = 45° and ∠R = (x + 45)°

by ANGLE SUM PROPERTY of a triangle:

Sum of all interior angles in any given triangle is always 180°.

⇒ In ΔPQR,

∠P +  ∠Q + ∠R = 180°

or,  x+ 45° +  (x + 45)° = 180°

⇒  2x + 90° =  180°

or, 2x =  180° - 90° = 90°

⇒ x = 90/ 2 = 45

or, x = 45

Hence,  ∠P  = x = 45°

and ∠R  = (x + 45)°  = (45 + 45)°  = 90°

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
