Answer:
if this is trigonometry, then x= 15 and y = 8.7 (1 d. p)
Step-by-step explanation:
use the three trig ratios as in sine , cosine and tangent.
To do this, first identify the sides so y is the adjacent, x is the opposite side and 10√3 is the value of the hypotenuse.
In this case, use sine and tangent :
sin 60=x/ 10√3
x = sin 60 * 10√3
x = 15
tan 60 = 15 /y
y = 15/ tan 60
y = 8.7 (1 d.p)
Step-by-step explanation:
optically, they are congruent.
so, it must be a reflection followed by a translation.
there is no 90° rotation. and the result cannot be created only by a reflection.
Total cost = a + (13a/100)
<u>Step-by-step explanation:</u>
Let the price of the monster truck be 'a'
He should pay 13% tax
Total cost = price of the truck + tax
Total cost = a + (13a/100)
The equation to represent the total cost is
Total cost= a + (13a/100)
You can 14 rows of 5 chairs, which also means you can do 5 rows of 14. Or 7 rows of 10 or 10 rows of seven. That's all I'm getting that doesn't exceed the 20 row limit.
Answer:
102cm²
Step-by-step explanation:
Surface Area = BH +Lp
B is the base area
H is the height of the Prism
L is the slant height
p is t perimeter of its base
B =1/2 ×3×4
B= 6cm²
H = 7cm
L = 5cm
P = 3cm+4cm+5cm
P = 12cm
Substitute
TSA = 6(7)+5(12)
TSA = 42+60
TSA = 102cm²
Hence the total surface area of the shape is 102cm²
