Answer:
x = 35
Step-by-step explanation:
we know that all triangles add up to 180
you first need to make an expression in which the angles equal 180
105 + 140 + x = 180
145 + x = 180
subtract 145 from both sides
x = 35
Answer:
A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a .
Step-by-step explanation:
We have been given an incomplete sentence. We are supposed to fill in the given blank.
A _______ represents the idea of "if and only if." Its symbol is a .
We know that "if and only if" stands for bi-conditional statement, which represents either both statements are true or both are false.
The symbol represent a bi-conditional statement.
Therefore, our complete statement would be: A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a .
Answer:
x = 2
Step-by-step explanation:
Given
Consider the perfect square closest to 41, that is 49
We require to add 8 to 41 to obtain 49
Now 8 = 2³
Thus
= = = 7 ← a rational number
Thus x = 2 is the required value for x
Answer: The ladder is 5.3 m long
Step by step solution
1. Draw out the scenario, ie a right triangle where the hypotenuse is the ladder, the wall is 4.5m and the angle the ladder and the ground makes 58 degree.
2. Soh, Cah, Toa
The wall is opposite, the ground is adjacent, and the ladder is hypotenuse
Sine (58) = 4.5/h
3. Solve for hypotenuse
h * sine (58) = 4.5
h = 4.5/sine (58)
h = ~ 5.3 m
(-3,6/5) is what I got. I hope it’s right
