Do you have a question about it ?
Answer:
14.3
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
14^2 + 3^2 = c^2
196 + 9 = c^2
205 = c^2
Take the square root of each side
sqrt(205) = sqrt(c^2)
14.31782106 = c
Rounding to the nearest tenth
14.3 = c
Answer:
Step-by-step explanation:
Note that 
.
Aha! We see a path to the solution!
We now know that our equation is actually 
.
We can divide both sides by 
to get 
.
By inspection or taking the logarithm base 2 of both sides, we see that 
.
So, the answer is 
and we're done!
Statements Reasons
1. Write all the given as you did 1. Given
2. <DBA and <DBC are right angles 2. Def of perpendicular lines
3. m<DBA = 90 3. Def of right angle
m<DBC = 90
4. m<DBA = m<DBC 4. Substitution
5. m<DBA = m<1 + m<3 5. Angle addition postulate
m<DBC = m<2 + m<4
6. m<1 + m<3 = m<2 + m<4 6. Substitution
7. m<3 = m<4 7. Subtraction prop of equality
Answer:
Square
Step-by-step explanation:
Properties of square:
1) All angles are right angle.
2) opposite sides are parallel
3) all sides are equal.
