Answer:
13.60
Step-by-step explanation:
use Pythagoras theorem
it is c²=a²+b²
c is hypotenus which is the longest side of a right angle triangle
--->now just put 8 on a and 11 on b
this gives us
c²= 8²+11²
c²= under the root 185
c² = 13.60147051
nearest hundredth is 13.60
hope you understood :)
Answer:
x = 13.60
Step-by-step explanation:
since it is a right angled triangle , we can use pythagoras theorem ,
hypotenuse^2 = base^2 + perpendicular^2
hypotenuse is the side opposite to the right angle .so here,
H = x .you can take base as 11 and perpendicular as 8
h^2 = p^2 + b^2
x^2 = 8^2 + 11^2
x^2 = 64 + 121
x =
x = 13.60

Answer:
1. The correct options are 2 and 4.
2. The measure of angle 6 is 60°.
Step-by-step explanation:
1.
It is given that a∥b , and c is not parallel to a or b. So, we can not establish any relationship among the angles on the line a,b and angles on the line c.
If a traversal line intersect two parallel line, then corresponding angles, alternate exterior angle and alternate interior angles are equal.
Therefore correct options are 2 and 4.
2.
It is given that AB∥CD and m∠3=120°.
Statements Reasons
m∥nm∠1=120° Given
∠5≅∠1 Corresponding angles are equal
m∠5=m∠1 Angle Congruence Postulate
m∠5=120° Substitution Property of Equality
m∠6+m∠5=180° Supplementary angle property
m∠6+120°=180° Substitution Property of Equality
m∠6=60° Subtraction Property of Equality
Therefore the measure of angle 6 is 60°.
- if you simplify it you would have to find factors of 45 that are perfect squares, for example, the square root of 9 times the square root of 5 is the square root of 45 so if you want to simplify it you would need to take the square root of 9 which is 3
so if you put in simplest form you would get 3 root 5
