Answer:
Area of given triangle is 939.15cm² and smallest altitude is 30.8cm
<h3>Solution:</h3>
We are given three sides of a triangle, Let the sides be :
We can find the area of the triangle with its three sides using Heron's Formula
- <u>Heron's </u><u>Formula</u>
Heron's formula was founded by hero of Alexandria, for finding the area of triangle in terms of the length of its sides. Heron's formula can be written as:

where ( s ) :

Therefore, for the given triangle first we will calculate ( s )

Now, Area of triangle will be:

Also, we have to find the smallest altitude, and the smallest altitude will be on the longest side. So,

Answer C. 2.00 Meters/second
1 kilometer = 1000 meter
1 hour = 3600 seconds
7.2 x 1000 = 7200
so 7200 meters an hour
or 7200 meters every 3600 seconds
7200/3600
we then want the 3600 to become one second to find meters per (1)second.
so 7200/3600 simplified = 2. 2 meters per second
answer C
Answer:
The length of the side adjacent to that angle is 26 units
Step-by-step explanation:
We are given
In a right triangle, the side opposite a 33 degree angle is 17 units
Firstly, we will draw diagram
we can use trig

now, we can solve for x


So,
The length of the side adjacent to that angle is 26 units
Answer:

Step-by-step explanation:
When two or more quantities have the same exponents, their bases can be multiplied together.
3x²+x-5=0
a = 3, b = 1, c= -5
-> ∆ ( delta ) = b²-4ac = 61 > 0
-> x1 =( -b+√∆ )÷ 2a =...
x2 = (-b-√∆)÷2a =...
p/s: do your teachers teach you how to use ∆ ( delta ) in maths calculation ? i live in europe and our teachers teach us that way. however, it is a rịght and fast way. you should learn it.
