Answer:
Value of x = 5
Explanation:
Given:
Angle 1 = 53°
Angle 2 = 78°
Angle 3 = (10x - 1)°
Find:
Value of angle x
Computation:
Using angle sum property of triangle
⇒ Angle 1 + Angle 2 + Angle 3 = 180
⇒ 53 + 78 + (10x - 1) = 180
⇒ 131 + 10x - 1 = 180
⇒ 10x + 130 = 180
⇒ 10x = 180 - 130
⇒ 10 x = 50
⇒ x = 50 / 10
⇒ x = 5
Value of x = 5
Answer:
d. lava flows volcanic mudslides called lahars
Explanation:
Mudflows of volcanic eruptions are the most dangerous, and are called lahars. A lahar is a type of mudflow or debris flow composed of a slurry of pyroclastic material, rocky debris, and water.
The fault is younger than the lower rocks but older those above it.
Explanation:
A fault found that cuts through lower rock layers but not those above it suggests that the fault is younger than the lower rock but older than those above it.
This interpretation is based on the principle of cross-cutting which states that "an intrusion or fault is younger than the rocks they cut through".
- In essence, an intrusion or fault cannot cut through a rock sequence unless it is already in place.
- This is why the fault that cuts through the rock layers is younger than the rock layers.
- But since it did not pass through the layers above, it is older than it.
