Part a= cuboid
Part b= To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.*I tried my best sorry*
Answer:
a=50
Step-by-step explanation:
a + 2a + 30 = 180
3a + 30 = 180
(-150 from both sides)
3a = 150
(Divide by 3 from both sides)
a = 50
Answer:
B. StartFraction R Y Over R S EndFraction = StartFraction R X Over R T EndFraction = StartFraction X Y Over T S EndFraction
i.e
=
= 
Step-by-step explanation:
Two or more shape or figures are similar when their sides and angles can be compared appropriately.
In the given figure, ΔRXY is within ΔRST. Since the two triangles are similar, then their length of sides can be compared in the form of required ratios.
So that by comparison,
=
= 
Therefore, the correct option to the question is B.
