Given △MON≅△PQR with MO=20 , MN=32 and PR=3x−10. Find the value of x.<br><br> show your work

aliya0001 [1]

Answer:

$x=14$

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

△MON≅△PQR

corresponding sides

MO≅PQ

MN≅PR

ON≅QR

corresponding angles

∠M≅∠P

∠O≅∠Q

∠N≅∠R

therefore

MN=PR

substitute the given values

$32=3x-10$

solve for x

$3x=32+10$

$3x=42$

$x=14$

$\\ \sf\longmapsto \dfrac{2}{3}x=10$

$\\ \sf\longmapsto \dfrac{2x}{3}=10$

$\\ \sf\longmapsto 2x=3(10)$

$\\ \sf\longmapsto 2x=30$

$\\ \sf\longmapsto x=\dfrac{30}{2}$

$\\ \sf\longmapsto x=15$
