Step-by-step explanation:

Given,

The angle is 63°

To find the value of z

We know that the diagonals of rhombus perpendicularly bisect each other.

Again,

z+63°+90° = 180° [ sum of all the triangle is 180°]

or, z = 27°

Can you answer this question as soon as possible.

Whitepunk [10]

Answer:

The intensity of the first earthquake is 6.31 times the second one

Step-by-step explanation:

The given formulae is M=log( $\frac{I}{S}$ )

Here for both the earthquakes the value of S is same.

Let the Intensity of the first earthquake be I1 and the second be I2.

Given M1=7.5

M2=6.7

Now M1=log( $\frac{I1}{S}$ )------1

M2=log( $\frac{I2}{S}$ )-----2

Now subtract 1 and 2 we get

M1-M2=log( $\frac{I1}{I2}$ )

I1/I2= $10^{M1-M2}$

I1=I2( $10^{0.8}$

I1=I2*6.31
