Answer:
x = 35° , y = 90°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
145° is an exterior angle of the triangle , then
y + 55° = 145° ( subtract 55° from both sides )
y = 90°
the sum of the 3 angles in a triangle = 180° , then
x + y + 55° = 180°
x + 90° + 55° = 180°
x + 145° = 180° ( subtract 145° from both sides )
x = 35°
Answer:
12+-8=4
Step-by-step explanation:
<em>this would be that same as 12-8=4, just keep the numbers but flip the negative into a positive number then change the equation into a subtraction problem if this confuses you.</em>

Answer:
A. ✓34
Step-by-step explanation:
The lengths of the legs of a right triangle are 3 and 5, the length of the hypotenuse will be:
= (✓(3² + 5²)
= ✓(9 + 25)
= ✓34
Answer:
base: 4
exponent: 3
numerator: 1
denominator: 64
Step-by-step explanation:
4^4 * 4^-2: Here you subtract 2 from 4 (just basic rules)
so you get 4^2/4^5
4^2/4^5: you subtract 5 from 2 (also basic rules)
then you would get 4^-3
To put in positive exponents you do 1/4^3
which gets you 1/64
