Answer:
here's your answer dear
2)
1)a) (-13)*(-15)
-13*-15
195
b) (-150)÷(-25)
6
2) supplementary = 180⁰
a) 108⁰
let the another angle be x⁰
108⁰+x⁰=180⁰
x⁰=180⁰-108⁰
x⁰= 72⁰
b) x⁰
let the another angle be x⁰
x⁰+x⁰=180⁰
2x⁰=180⁰
x⁰=180⁰/2
x⁰=90⁰
3) complementary angle =90⁰
a) 60⁰
let the other angle be x⁰
x⁰+60⁰=90⁰
x⁰=90⁰-60⁰
x⁰=30⁰
b) 35⁰
let the other angle be x⁰
x⁰+35⁰=90⁰
x⁰=90⁰-35⁰
x⁰=55⁰
