Answer:
4+4=8 quickmaf
Step-by-step explanation:
Ggg4 fg5*6
A^2 +a-6. You use the method of foiling where you multiply the first two terms, the the outside terms, the inside terms, then the last terms. You would do a•a, then a•-2 the a•3 then 3•-2. You would get a^2 -2a +3a -6. Then combine like terms to get your answer.
Answer:
x = 48°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (90 + 42)° = 180° - 132° = 48°
1/2 (Base x height) = area
1/2 (4*x)=10
2x=10
X=5
The height is 5 units
