Answer:
- perimeter = 6+2√73 ≈ 23.09 units
- area = 24 units²
Step-by-step explanation:
It can help to draw a figure.
The altitude of this isosceles triangle is 8 units, and it splits the base into equal lengths of 3 units. Using the Pythagorean theorem, we find the length of a side to be ...
BC = AC = √(3² +8²) = √73
The perimeter is the sum of the lengths of those two sides and the base:
P = 2(√73) +6 ≈ 23.088 . . . units
The area is given by the formula ...
A = 1/2bh
A = (1/2)(6 units)(8 untis) = 24 units²
__
The perimeter is 6+2√73 ≈ 23.09 units.
The area is 24 units².
To determine the measure of the angle with the cosine value equal to 0.208, we have to use the inverse trigonometric functions. In this number, we have the arccosine which is also written below.
cos⁻¹(0.208) = 77.9948⁰
Therefore, the measure of the angle with cosine equal to 0.208 rounded to the nearest thousandth is <em>77.995⁰</em>.
Answer:
The correct option is (a).
Step-by-step explanation:
We need to find the expression that is equivalent to 1.5(6x+3y)+2x-0.05y.
Firstly opening brackets as follows :
Now taking x terms and y terms together
So, 1.5(6x+3y)+2x-0.05y is equal to 11x+4.45y.
Answer: x × 15.6
The word "times" in the question indicates that we need to multiply a number x with 15.6.
