Step-by-step explanation:
When there are more than 1 brackets , there is a specific order of opening those brackets. First we open the bar , then round brackets , then curly brackets & then square brackets.
Using the order , let's solve this.
25-[20-{10-(7-5-3)}]
=> 25-[20-{10-(7 - 8)}]
=> 25-[20-{10 - (-1)}]
=> 25-[20- {10 + 1} ]
=> 25-[20 - {11}]
=> 25 - [ 20 - 11 ]
=> 25 - [9]
=> 25 - 9
=> 16

Answer:
30.8, 37
Step-by-step explanation:
First, we know that the angles in a triangle add up to 180, so 180-75-48= m∠G=57°. Then, using sohcahtoa, we have tan(G) = DF/FG = DF/20. tan(G) ≈ 1.54, so 20(1.54)=DF≈ 30.8
Next, using sohcahtoa, we have cos(G) = FG/DG = 20/DG. cos(G)≈0.54, and 20/0.54=DG ≈ 37
Consider the intersecting lines shown. Which of the following statements is true?
Question 10 options:
A)
∠y ≅ ∠z
B)
∠x ≅ ∠y
C)
m∠x + m∠y = 180°
D)
m∠x + m∠y = 90°
Answers
Answer:
C. m∠x + m∠y = 180
Step-by-step explanation:
The two straight line in the diagram intersect each other to form two pairs of vertical angles. These are <x and <z, and <y and w.
The only statement from the given options that is true is m∠x + m∠y = 180.
This is because they are angles in a straight line. The sun of angles in a straight line is 180°.

The weight of body is 420N. calculate its mass.
Answers
Answer:
mass = 42 kg
Step-by-step explanation:
We know that we have the formula that
W = m * g
Then
given
weight (w) = 420
g = 10 m/s²
then
W = m* g
420 = m * 10
m = 420/10
m = 42 kg
Hope it helps :)
Answer:
Step-by-step explanation: weight = 420N
mass= ?
we know,
weight = mass . acceleration due to gravity
or, 420 = mass . 9.8
therefore mass = 42.85 kg
