An acute, isosceles triangle has a vertex angle measuring 78 degrees. what are the measures of the other two angles?

Step-by-step explanation:

180-78=102

102/2=51

the other 2 angles are 51 degrees

Step-by-step explanation: since it is an isoceles triangle two sides are equal thus 2 angles are equal.

Therefore, let's take the two angles as x

78+ x+x = 180 ( angle sum property)

Thus , 2x= 180-78

X = 102/2

X= 51 degrees

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
