x = 14

Step-by-step explanation:

4x° + (3x + 20)° + (3x + 20)° = 180° (sum of interior angles; isocleces triangle)

10x + 40 = 180

10x = 140

x = 14

The diagram shows a right-angled triangle.

Otrada [13]

Answer:

h ≈ 9.9 cm

Step-by-step explanation:

By applying tangent rule for the given angle in the given right triangle,

tan(51°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(51°) = $\frac{h}{8}$

h = 8 × tan(51°)

h = 9.879

h ≈ 9.9 cm

Therefore, measure of side 'h' is 9.9 cm.
