Answer:
Step-by-step explanation:
1) Isosceles triangle
2) Right angled triangle
3) Scalene triangle
4) Equilateral triangle
5) Right angled triangle
6) Scalene triangle
7) Equilateral triangle
8) Scalene triangle
9) a) Equilateral triangle
9) b) Scalene triangle
9) c) Isosceles triangle
9) d) Right angled triangle
Note: Right angled triangle - If one angle is right angle, then it is Right angled triangle
Isosceles triangle: If two angles or two sides are equal, then it is Isosceles triangle.
Scalene triangle: If all three sides or three angles have different measurement, then it is Scalene triangle.
Equilateral triangle: If all the three sides are equal or all the three angles are equal, then it is Equilateral triangle
By the rule of 3 simple:
53/100 = x/113100
x = 53*113100/100 = 59943
Answer:
1) u > 4
2) 7 < u
3) u < 4
4) 7 > u
Step-by-step explanation:
1) subtract 6 - 2
2) add 3 + 4
3) subtract 4 on both sides (8-4)
4) subtract 9 - 2
Area of triangle = 1/2 absinC
area of triangle = 1/2 (12) (24) sin(30°)
area of triangle = 72 unit²
