Determine which 2 triangles are similar to each other. the images are not drawn to scale.

Thus, ΔQRS is similar to ΔHIJ.

Explanation:

Consider the provided figures.

In ΔQRS

∠Q=53° and ∠R=90°

Therefore,

∠Q +∠R + ∠S = 180°

53° + 90° + ∠S = 180°

∠S = 37°

Now consider the ΔHIJ

In ΔQRS

∠I=37° and ∠J=90°

∠I +∠J + ∠H = 180°

37° + 90° + ∠H = 180°

∠H = 53°

Now, from the above calculation it is clear that ΔQRS is similar to ΔHIJ.

Thus, ΔQRS is similar to ΔHIJ.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
