How do I find x and y
Usimov [2.4K]
First you would have to find the third angle in the triangle which you would do by adding 63+61 and subtracting the resulting number from the total degrees in a triangle. From there, you would calculate x and y using the knowledge that angles on a line equal 180.

Answer:

see below

Step-by-step explanation:

1.  < 4 is the exterior angle of a triangle   given

2.  <1 + <2 + <3 =180   basic property of triangles

3.  <3 + <4 are a linear pair    <3 and <4 are adjacent and form a straight line

4. <3 and <4 are supplementary angles  supplementary angles are linear pairs

5.  <3 + <4 = 180   The definition of supplementary angles are that they add to 180 degrees

6.  <1 + <2 + <3 = <3+ <4  Substitute <3 + <4  for 180 in equation from step 2

7 <1 + <2 = <4   Subtract <3 from each side using the subtraction property of equality

Jocelyn just accepted a job at a new company where she will make an annual salary of $70000. Jocelyn was told that for each year
Oksanka [162]

Answer:

$80,500

55,500 + 1,500t

Step-by-step explanation:

The question is an arithmetic progression series

Where,

a= first term

d= common difference

n= number of terms

a = $70,000

d= $1,500

n= 8 years

8th term = a + (n-1) d

= 70,000 + (8-1)1500

= 70,000 + 7(1500)

= 70,000 + 10,500

= $80,500

Jocelyn salary after 8 years is $80,500

Solve for when n = t

t th term = a + (n-1)d

= 70,000 + (t - 1)1500

= 70,000 + 1,500t - 1,500

= 55,500 + 1,500t

t th term = 55,500 + 1,500t

What is the height of a triangle that has an area of 60 yards^2 and a base of a length of 12 yards?
zmey [24]
For a triangle:
A=\frac{b \times h}{2}
60=\frac{12\times h}{2}
120=12h
h=\frac{120}{12}
h=10yrd
