Given:
In a right angled triangle ABC the perpendicular and the base measure 3 cm.
To find:
The hypotenuse and three trigonometric ratios.
Solution:
Pythagoras theorem:
Use Pythagoras theorem in triangle ABC.
The three trigonometric ratios are
Similarly,
And,
Therefore, the hypotenuse is 
cm and three trigonometric ratios are 
.
Answer:
$68.60
Step-by-step explanation:
If the original price is $98
30% = 0.03
0.30*98=29.40
Then, 98−29.40=$68.60
Answer:
x+7=90 find the value of x
Step-by-step explanation:
Answer:
the schedule and the algebraic expression
Answer:
29° + (x - 5)° = 180°
29 + x - 5 = 180
29 - 5 + x = 180
24 + x = 180
24 - 24 + x = 180 - 24
x = 156
Step-by-step explanation:
A straight line is 180°.
Set all angles (29° and (x - 5)°) equal to 180°.
Then solve for x.
