B. We know the area of a triangle is 12 cm2. We also know the height is 6 cm. Find the base of the triangle (hint: you can use the formula in parta) cm help please

The base of traingle is 4cm.

Step-by-step explanation:

Given that the area of triangle is A = 1/2×b×h where b represents base and h is height. So you have to substitute the values into the expressions and solve it :

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
