Find the measure of each angle
Leno4ka [110]
Since this triangle is an isosceles triangle, two of its angles are going to be equal. We know that all the angles in a triangle are equal to 180o. 

Step 1: 180 - 98 = 82

Step 2: divide the sum of the two angles (82) to give me the measurement of one of the angles 

82/2 = 41

Dafna1 [17]

Answer:

110

Step-by-step explanation:

Formula for SA of a rectangular prism:

SA = 2lh + 2lw + 2wh

Given dimensions:

l = 1

w = 7

h = 6

Simply plug in these given dimensions into the SA formula to get the answer

SA = 2lh + 2lw + 2wh

Substitute given variables

SA = 2(1)(6) + 2(7)(1) + 2(6)(7)

* Multiply parentheses that are next to each other *

SA = 2(6) + 2(7) + 2(42)

* Multiply again *

SA = 12 + 14 + 84

*add*

SA = 110
