Answer:
38°
Step-by-step explanation:
The measure of required angle can be obtained by using cosine law.
From the given triangle we find that:
a = 5, b = 3, c = 7,
Since,
cos (A) = (b^2 +c^2 - a^2) /2bc
Therefore,
cos (A) = (3^2 + 7^2 - 5^2) /(2*3*7)
cos (A) = (9 + 49 - 25) /(42)
cos (A) = (33) /(42)
cos (A) = 0.785714286
A = arccos(0.785714286)
A = 38.213210675°
A = 38°
Answer:
c
Step-by-step explanation:
Step-by-step explanation:
-3x + 4 > 25
-3x > 21 (subtract 4 on both sides)
x < -7. (divide -3 on both sides, flip the sign)
Answer:

Step-by-step explanation:
Given



Required
Find Y
To do this, we make use of the mid-point formula
i.e.

WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:


The mid-point of ZY is:

Equate both values of M

Multiply both sides by 2

By comparison:








Hence:

Honestly I don’t get the question
