Answer:
As I divided in the picture,
Total area = area of triangle + area of 2 rectangles
= base x height/2 + length1 x width1 + length2 x width2
= 15 x (15 + 3 + 5 - 3)/2 + 3 x 4 + 8 x (3 + 5)
= 226
Hope this helps!
:)
x < - 
add
to both sides
- 3x >
+ 
- 3x >
( divide both sides by - 3 )
note that when we divide/ multiply by a negative quantity we must reverse the inequality symbol
x < - 
24.3
bcoz to round to tenths place need to chk with hundreths place.
As 1 is in hudredths place so the digit in tenths place remains the same
Answer: 
Step-by-step explanation:
Since, in the triangle abc,
ab = 10√91 unit, bc = 30 unit, ca = 100 unit and m∠b = 90°
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Which is the required value of tan(∠a).
Answer:
y ≈ 16.33
Step-by-step explanation:
∆SPQ is a 30-60-90 right triangle
PS:QS:PQ = 1:2:√3
QS/PQ = 2/√3
QS/PQ = QS/10
QS/10 = 2/√3 Multiply each side by 10
QS = 20/√3
∆RSQ is a 45-45-90 right triangle.
∴ RS = QS = 20/√3
RS² + QS² = QR²
(20/√3)² + (20/√3)² = y²
400/3 + 400/3 = y²
800/3 = y² Take the square root of each side
y = √(800/3)
= 20√(2/3)
= (20√6)/3
≈ 16.33
