You need to know these two formulas:
For example,
Find out the statement true regarding the diagram given in the question
Answer
the statement is true regarding the diagram is
m∠WXY + m∠YXZ = 180°
REASON
As shown in the diagram
∠WXY and ∠ YXZ are supplementary angles.
Supplementary angle definition
Two Angles are said to be Supplementary when there sum is equal to 180 °.
thus we get
m∠WXY + m ∠YXZ = 180 °
Therefore the m∠WXY + m∠YXZ = 180° is the true statement.
Answer:
1.43 as a decimal
Step-by-step explanation:
%143 = 1.43
Where's the equation that contains "z"?
Answer:
10
Step-by-step explanation:
with reference angle 30°
perpendicular (p) = 5
hypotenuse (h) = x
Now
sin 30° = p / h
1 / 2 = 5 / x
x = 10
Hope it will help :)
