A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape. please make me brainliest
Answer:
Let Hassan score be X
Then Dionnie score will be X + 4
: the sum of Hassan and Dionnie is 180
X + ( X + 4 ) = 180
X + X + 4 = 180
COLLECTING LIKE TERMS
2X = 180 – 4
2X = 176
DIVIDING EACH TERM BY 2
2X/2 = 176/2
X = 88
: Hassan scored 88 and Dionnie score 92

Answer:
95.9 cm^2
Step-by-step explanation:
this figure is composed of two semicircles. the area of each semicircle would be determined and then added together.
area of a semicircle = 1/2 nr^2
r = radius
n = 22/7
bigger semicircle
1/2 x (22/7) x (6^2) = 56.57cm^2
smaller circle = 1/2 x (22/7) x (5^2) =39.29cm^2
Sum of the areas = 56.6 + 39.3 = 95.9 cm^2
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
