Can you assist me? Thanks.

It’s been a while since I’ve done geometry, but I think this is right.
Because we are dealing with a rhombus: angles X and A are the same, so we use this to solve for x like any other algebraic expression.
After we have found x (24), we can also apply the knowledge that since angles X and M are complementary they will form a 180° line when added.
Substitute the expression for angle X with the solved for expression and subtract it from 180°. And bam! Angle M

Answer: 1.303639
Step-by-step explanation:
The t-score for a level of confidence is given by :_
, where df is the degree of freedom and
is the significance level.
Given : Level of significance :
Then , significance level :
Sample size :
Then , the degree of freedom for t-distribution:
Using the normal t-distribution table, we have
Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639
