Answer:
a)x+69+73=180°{sum of angle of triangle}
b)
let, another a unknown side be 'p'
p=65°{alternate angle}
65+65+z=180°{sum of angle of triangle.}let ule
130+z=180
z=180-130
z=50°
- y+z+65°=180°{straight angle}
- y+115=180°
- y=180-115
- y=65°
z=x{alternate angle.}
x=50°
so, x=50°, y=65°, z=50°
c)z+19°=180°{straight angle}
z=180-19
z=161°
- z=y{co_interior angle}
- y=161°
d) 67+35+x=180°
x=180-102
x=78°
- y+67=180°{straight angle}
- y=180-67
- y=113°
- 35+z=180°{straight angle}
- z=180-35
- z=145°
2)
3x+10+2x-5+x-5=180°{sum of angle of triangle}
6x=180°
x=180/6
x=30°
hope it helps.
I think 289 x 3.14 which is 907.46 m2
So the answer should be = 907.46 meter square
Hope its help
Answer: 73
Step-by-step explanation:
Answer:
$22.50
Step-by-step explanation:
10% = 10/100 = 0.1
So 10% of $25 = 0.1 x 25 = 2.5
Therefore, if the price of the meal is 25 with 10% off:
25 - 2.5 = $22.50
Or,
If the meal is bought with a 10% off coupon, that means the cost of the meal will now be 90% of the original price (as 100% - 10% = 90%).
90% = 90/100 = 0.9
25 x 0.9 = 22.5
