Answer:
Step-by-step explanation:
the formula for an arithmetic sequence is
a, a+d,a+3d,a+3d etc, where d is the common difference
we have the terms -6, 13,23
first term is -6
-6+19=13
however, 13+10=23
this is not an arithmetic sequence
Answer:
h = 57.73 m
Step-by-step explanation:
We have,
The angle of elevation of the top of tower to be 30 degree
James is 100 m away horizontally from the base of the tower.
It is required to find the height of the tower.
Here, angle is 30 degree
Base, b = 100 m
Let h is the height of the tower. The relation between base and height is given by :
So, the height of the tower is 57.73 m.
Answer:
the corresponding angles are equal in similar figures.
Step-by-step explanation:
When two figures are similar then the corresponding angles of the two figures are equal. the side of the figures are in proportional.
for example, when triangle ABC is similar to triangle DEF
then the corresponding angles are equal
<A=<D
<B=<E
<C=<F
so the corresponding angles are equal in similar figures.
