It is given that ️PQR & ️UVW are congruent to each other. According to CPCT, the corresponding angles in 2 triangles willl have the same measure. So, ∠R = ∠W, i.e, (10x - 18)° = 8x°

$\mathfrak{10x - 18 = 8x}$

$\mathfrak{10x - 8x = 18}$

$\mathfrak{2x = 18}$

$\mathfrak{x = \dfrac{18}{2}}$

$\underline{\mathfrak{x = 9}}$

Measure of ∠R :

$\mathfrak{8x}$

$\mathfrak{8(9)}$

$\boxed{\mathfrak{72^{\circ}}}$

Solve the following word problems.

aleksandr82 [10.1K]

Answer:

Step-by-step explanation:

Let a , b , c & d be the no. of chairs in hall A , B , C & D respectively.

Given,

b = 4a

c = a + 15

d = a + 8 + 4a = 5a + 8

Now,

Total no. of chairs (T) = a + b + c + d

= a + 4a + a + 15 + 5a + 8

= 11a + 23

Now,

Average chairs in each hall (Avg) = T/4

= (11a + 23)/4
