Write 6.384 correct to 1 decimal place ?=6
Answer:
Smallest angle = 23
Middle angle = 23 + 44 = 67
Right angle = 90
Step-by-step explanation:
Givens
Let the smallest angle = x
Let the middle angle = x + 44
Let the right angle = 90 which it always does.
All triangles = 180 degrees.
Equation
x + x + 44 + 90 = 180
Solution
2x + 44 + 90 = 180 Combine the left
2x + 134 = 180 Subtract 134 from both sides
2x +134-134 = 180 - 134 Combine
2x = 46 Divide by 2
2x/2 = 46/2 Do the division
x = 23
Answer:
96 square inches.
Step-by-step explanation:
From given picture we see that
BC=8 in
AD=10 in
Given that
AD=AB
Then AB=10 in
Apply Pythagorean theorem in triangle ABC to find AC
take square root
Then area of triangle ABC
There are total 4 congruent triangles.
Then total area of the given figure = 4(24)=96 square inches.
The answer is B, each term is being multiplied by 0.5 and the next two terms are 1.25 and 0.625.
Hope this helps!
