The area of image is: 41 square units
<h2>Step-by-step explanation:</h2>The area of the image is equal to:
Area of square CDEF+Area of right angled triangle ΔBFA
In square CDEF we have:
The lengths of the side of the square= 4 units
Hence, the area of square is: side²
i.e. Area of square= 4²=16 square units
Also, in ΔBFA we have:
The base of the triangle is: BF=CB+CF=6+4= 10 units
Also, height of the triangle is: FA= 5 units
Hence, we have area of ΔBFA as:
Area= 1/2×BF×FA
i.e.
Area= 1/2×10×5
i.e.
Area= 25 square units
Hence, the area of image is: 16+25
i.e.
Area of image= 41 square units
Answer:
Step-by-step explanation:
Given that the angles A, B, C in a Triangle form an arithmetic sequence where A=23 degrees.
The nth term of an Arithmetic sequence is given by the formula:
Where:
a=first term
n=number of term
d=common difference
In this case,
The sum of angles in a triangle is 180 degrees. Therefore:
∠A+∠B+∠C=180 degrees
Therefore:
Angle C,
