Here is the answer, the summation of the angles inside any triangle = 180 . Also, the same thing for any angles for straight line = 180.
BC = a
AC = b
ACB = C
To find the area of such triangle we are going to use the formula;
1/2 * a * b * sine C
Substitute values.
1/2 * 4 * 4 * sine 45
= 5.65^2
Therefore the area of the triangle is 5.65^2
10+10+10+10+10+1+1+1+1+1+1+1+1=58
Answer:
21
Step-by-step explanation:
7x3=21
21/3=7
you just have to use inverse operations
(: hope this helps
The angle will be 22 degrees since anything bigger that 90 degrees wont work.
