= - 1 - 2(1) - 3 + 5
= - 1 - 2 - 3 + 5
= - 6 + 5
= - 1

Answer: The fourth option, 54°
Step-by-step explanation:
In the graph we can see that we have a triangle rectangle.
I will call each angle as the letter where it is located, the bottom angle is D, the upper left angle is C and the upper right angle is B (this last one is the angle we want to find)
This means that if the bottom angle, the angle located at D, is equal to 36°, we have that the angle located at C is equal to 90°.
And as you know, the sum of all the internal angles of a triangle must be equal to 180°, so we have:
D + C + B = 180°
90° + 36° + B = 180°
B = 180° - 90° - 36° = 54°
The correct option is the fourth one.
Answer: B
x looks like .9 so if -.9 + 3 = -2.1 then you can see that's the answer on the number line, hope it helps, I'm 80% sure it's right
First you gotta remove all parentheses by multiplying the factors next remove all grouping if the terms are containing exponents then you combine all terms and lastly you combine the constants
