Sci = π . 2 . 2 = 12,56 ⇒ 1/2 Sc1 = 1/2 . 12,56 = 6,28
Srec = 6 . 4 = 24
S= 6,28 + 24 = 30,28
the answer is 30,28
ok done. Thank to me :>
Answer:
85 degrees
Step-by-step explanation:
the sum of supplementary angles=180
155+ angle in the triangle=180
angle=180-155
angle=25 degrees
the sum of angles of triangle=180
25+60+x=180
85+x(inside triangle)=180
x=180-85
x=95
angle with (?):
the sum of supplementary angles=180
95+(?)=180
(?)=180-95
(?)=85 (An exterior angle of a triangle is equal to the sum of the opposite interior angles)
the last one,,,,,,,,,,,,,,,,,,,,,,,,,
