Answer:
36 feet
Step-by-step explanation:
shadow/height = shadow/height
11/6 = 66/h
h = 66 * 6 / 11
h = 36
Answer:
The man would be 40 years old.
Step-by-step explanation:
Blood pressure as function of age:
Is given by the following equation:
Find the age of a man whose normal blood pressure measures 129 mmHg.
This is A for which P = 129. So
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
In this question:
Quadratic equation with . So
Age has to be a positive number, so rounding to the nearest year:
The man would be 40 years old.
Area of isosceles triangle is 63.98 square units.
<u>Solution:</u>
Note: Refer the image attached below
Given that leg of an isosceles triangle is 16; Measured of one of the angle is 150; Need to determine area of triangle.
Consider the figure ABC is required isosceles triangle
From given information,
AC = CB = 16 and
So we have two sides and angle between them. Let us use law of cosine
On applying law of cosine on triangle ABC we get,
Now we are having three sides of triangle,
AB = 30.91; BC = 16 and CA = 16
As three sides are given, we can apply heron’s formula to determine area of triangle ABC. According to herons formula,
In our case a = AB = 30.91; b = BC = 16; c = CA = 16
