What’s the value of X In this????
kkurt [141]

Answer:

x = 68 degrees

Step-by-step explanation:

Step 1: We know this is a isosceles triangle

Since we know it is a isosceles triangle it has 2 of the same angle so the unknown side(not x) is 59

Step 2: Use the 2 angles to find 'x'

Angles in a triangle add up to 180 so we subtract 59 x 2 from 180 to get 68

Therefore angle x is 68 degrees

$1,000, 7% , 2years
Simora [160]

Answer:

$1,140, or $1,144.9

Step-by-step explanation:

70 is 7% of 1,000

70 x 2 = 140

140 + 1,000 = 1,140

Or, if you mean 7% compounded annually then....

1,070 after first year.

7% of 1,070 = 74.9

74.9 + 1,070 = 1,144.9
