Answer:

The value of 'x' is 17.

Step-by-step explanation:

Given:

Δ IJK ≅ ΔPQR

m∠I = 3x + 4

m∠P = 72 - x

To Find:

x = ?

Solution:

Δ IJK ≅ ΔPQR ...........Given

If two triangles are congruent then the corresponding angles of congruent triangles are congruent.

∴∠ I ≅ ∠ P ........corresponding parts of congruent triangle (CPCT)

Substituting the values we get

$3x+4=72-x\\\\3x+x=72-4\\\\4x=68\\\\\therefore x=\dfrac{68}{4}=17\\\\\therefore x =17$

The value of 'x' is 17.

Find the value of root 121 + 3 over root 125

NemiM [27]

Answer:

$\mathrm{Decimal:\quad }\:1.25219\\\frac{14\sqrt{5}}{25}$

Step-by-step explanation:

$\frac{\sqrt{121}+3}{\sqrt{125}}\\\sqrt{125}=5\sqrt{5}\\=\frac{\sqrt{121}+3}{5\sqrt{5}}\\\sqrt{121}=11\\=\frac{11+3}{5\sqrt{5}}\\\mathrm{Add\:the\:numbers:}\:11+3=14\\=\frac{14}{5\sqrt{5}}\\\mathrm{Rationalize\:}\frac{14}{5\sqrt{5}}:\quad \frac{14\sqrt{5}}{25}\\=\frac{14\sqrt{5}}{25}$
