Answer:
69 degree
Step-by-step explanation:
Using cosine formula again :))
So we have
BC^2 = AB^2 + AC^2 - 2*AB*AC*cosA
BC^2 = 32^2 + 28^2 -2*28*32*cos56
BC = 28.3884 cm
So B:
AC^2 = AB^2 + BC^2 - 2*AB*BC*cosB
CosB=0.3559
B=69.14 degree
Answer: The answers are given below.
Step-by-step explanation: Given that we are assembling pieces of an iron gate to complete a fence. The finished gate will look like the figure as given in the question.
Part 1: We can clearly see in the picture given that pieces 1 and 2 are placed at an angle of 90° to each other. Therefore, the pieces 1 and 2 are perpendicular to each other.
Part 2: Also, it can be seen that in the centre of the gate, the rectangular sections 5 and 6 are placed at an angle of 0° to each other. Therefore, sections 5 and 6 are parallel to each other.
Thus, 1 and 2 are perpendicular; 5 and 6 are parallel to each other.
Triangles interior angles addition 180 degree
3+2+?=180
5+?=180
?=180-5
?=175
Answer:
D. The hiker would climb up 46 meters
Step-by-step explanation:
It would make the negative cancel out and would make it 0. 0 is sea level
Answer:
We simplify the equation to the form, which is simple to understand
5x+25=10
We move all terms containing x to the left and all other terms to the right.
+5x=+10-25
We simplify left and right side of the equation.
+5x=-15
or this is another way
Simplifying
5x = 25 + -10
Combine like terms: 25 + -10 = 15
5x = 15
Solving
5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '5'.
x = 3
Simplifying
x = 3
We divide both sides of the equation by 5 to get x.
x=-3
