The answer is The third angle measures 120 degrees

Step-by-step explanation:

I know this because a triangle has angle sum of 180 and so if you know two of the sides then you can add them together; 30+30 = 60 then substract it from 180; 180-60 and that would equal 120 degrees.

A rectangle hale card has a length of 3/10 and a width of 4/5 find the perimeter
postnew [5]

Answer:

22/10 or 2 and 1/5

Step-by-step explanation:

To find the perimeter, add all sides together. Since it's a rectangle, the other sides are the same measurement as the ones given. Add 3/10, 3/10, 4/5, and 4/5 together. To do this, find a common denominator. The lowest common denominator is 10 so multiply the 4/5 by 2/2 to get the denominator to be 10. Now, add 3/10, 3/10, 8/10, and 8/10. It adds up to 22/10 but if you don't want an improper fraction, simplify it to 2 and 1/5.

there is a line that includes the point (1,5) and has a slope of 15. what is its equation in slope-intercept form?​
olchik [2.2K]

Answer:

y = 15x - 10

Step-by-step explanation:

slope is given: 15

(x, y) is given: (1, 5)

plug values into y = mx + b:

5 = (15)(1) + b

solve for b:

b + 15 = 5

b = -10

rewrite the equation:

y = 15x - 10

(-4)(-4) use an exponent to rewrite the expression
DiKsa [7]
For this case we have the following expression:
<span> (-4)(-4) &#10;
 By properties of exponents we have:
 Same basis, the exponents are added.
 We have then:
 (-4)^{1+1}
 Then, rewriting the exponent we have:
 (-4)^{2}
 Therefore, an exponent to rewrite the expression is:
 2
 Answer:
 
(-4)^{2}
 an exponent to rewrite the expression is 2.</span>
