Answer:
1. A = 40 units²
2. A = 72 units²
3. B) 45
Step-by-step explanation:
1. This shape comprises 4 congruent triangles with base of 5 units and height of 5 units.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 4(1/2 x 5 x 4)
= 40 units²
2. This shape comprises two pairs of congruent triangles.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 2(1/2 x 2 x 6) + 2(1/2 x 10 x 6)
= 72 units²
3. Count the number of shaded squares:
9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 units²
your answer is the first one, MNO is similar to GHK
the sum of the interior angles of a triangle is 180°
MNO
180 - 22 - 79 = 79° (angle N)
GHK
180 - 79 - 79 = 22° (angle K)
From here you see that they have the same angles, so they are similar.
Answer:
x= 14.84cm
Step-by-step explanation:
cos(52)=x/28
cos(52)*28=x
x=14.84 cm
